NCN5192 http://onsemi.com 8 functional description the NCN5192 is a single-chip modem for use in highway addressable remote transducer (hart) field instruments and masters. the modem ic contains a transmit data modulator with signal shaper, carrier detect circuitry, an analog receiver, demodulator circuitry and an oscillator, as shown in the block diagram in figure 1. the modulator accepts digital data at its digital input txd and generates a trapezoidal shaped fsk modulated signal at the analog output txa. a digital ?1? or mark is represented with a frequency of 1200 hz. a digital ?0? or space is represented with a frequency of 2200 hz. the used bit rate is 1200 baud. the demodulator receives the fsk signal at its analog input, filters it with a band-pass filter and generates 2 digital signals: rxd: received data and cd: carrier detect. at the digital output rxd the original modulated signal is received. cd outputs the carrier detect signal. it goes logic high if the received signal is above 100 mvpp during 4 consecutive carrier periods. the oscillator provides the modem with a stable time base using either a simple external resonator or an external clock source. detailed description modulator the modulator accepts digital data in nrz form at the txd input and generates the fsk modulated signal at the txa output. pc20101117.1 sine shaper numeric controlled oscillator modulator txa txd rts fsk_out figure 4. modulator block diagram a logic ?1? or mark is represented by a frequency f m = 1200 hz. a logic ?0?or space is represented by a frequency f s = 2200 hz. t t bit = 833  s ?1? = mark 1.2 khz ?0? = space 2.2 khz kvde20110407.5 t bit = 454  s figure 5. modulation timing the numeric controlled oscillator (nco) works in a phase con tinuous mode preventing abrupt phase shifts when switching between mark and space frequency. the control signal ?request to send? (rtsb) enables the nco. when rtsb is logic low the modulator is active and NCN5192 is in transmit mode. when rtsb is logic high the modulator is disabled and NCN5192 is in receive mode. the digital outputs of the nco are shaped in the wave shaper block to a trapezoidal signal. this circuit controls the rising and falling edge to be inside the standard hart waveshape limits. figure 6 shows the transmit-signal forms captured at txa for mark and space frequency. the slew rates are sr m = 1860 v/s at the mark frequency and sr s = 3300 v/s at the space frequency. for aref = 1.235 v, txa will have a voltage swing from approximately 0.25 to 0.75 v dc . t (ms) 0 v txa 0.5 v 1 2 t (ms) v txa ?1? = mark; f m =1.2 khz ?0? = space; f s =2.2 khz kvde2011040 8 0 1 2 sr m = 1860 v/s 0.5 v sr s = 3300 v/s 0. 5 v 0.5 v figure 6. modulator shaped output signal for mark and space frequency at txa pin. demodulator the demodulator accepts a fsk signal at the rxa input and reconstructs the original modulated signal at the rxd output. figure 7 illustrates the demodulation process. t bit idle (mark) lsb msb idle (mark) t bit 8 data bits d0 start d1 d2 d3 d4 d5 d6 d7 stop par ?0? ?1? ?0? ?1? ?0? ?1? ?0? ?0? ?0? ?1? fsk_in rxd pc20101013.4 figure 7. modulation timing this hart bit stream follows a standard 11-bit uart frame with start, stop, 8 data ? and 1 parity bit. the communication speed is 1200 baud.
NCN5192 http://onsemi.com 9 receive filter and comparator the received fsk signal first is filtered using a band-pass filter build around the low noise receiver operational amplifier ?rx hp filter?. this filter blocks interferences outside the hart signal band. rx comp rx hp filter rxaf rxa rxafi aref demodulator hart in 1.235 v dc c 1 c 2 c 3 r 1 r 2 r 3 r 4 r 6 r 5 c 4 pc20101118 .2 15 m  figure 8. demodulator receive filter and signal comparator the filter output is fed into the rx comparator. the threshold value equals the analog ground making the comparator to toggle on every zero crossing of the filtered fsk signal. the maximum demodulator jitter is 12 % of one bit given the input frequencies are within the hart specifications, a clock frequency of 460.8 khz ( 1.0 %) and zero input (rxa) asymmetry. carrier detect circuitry low hart input signal levels increases the risk for the generation of bit errors. therefore the minimum signal amplitude is set to 80 ? 120 mvpp. if the received signal is below this level the demodulator is disabled. this level detection is done in the carrier detector. the output of the demodulator is qualified with the carrier detect signal (cd), therefore, only rxa signals large enough to be detected (100 mv p-p typically) by the carrier detect circuit produce received serial data at rxd. figure 9. demodulator carrier and signal comparator rxd cd demodulator logic rx comp carrier detect counter carrier comp demodulator rxafi aref cdref 15 m  filtered hart in 1.235 v dc v aref ?80mv kvde20110407.6 rxd_enh the carrier detect comparator shown in figure 9 generates logic low output if the rxafi voltage is below cdref. the comparator output is fed into a carrier detect block. the carrier detect block drives the carrier detect output pin cd high if rtsb is high and four consecutive pulses out of the comparator have arrived. cd stays high as long as rtsb is high and the next comparator pulse is received in less than 2.5 ms. once cd goes inactive, it takes four consecutive pulses out of the comparator to assert cd again. four consecutive pulses amount to 3.33 ms when the received signal is 1200 hz and to 1.82 ms when the received signal is 2200 hz. the dif ference between rxd and rxd_enh is evident when cd is low: rxd is then also low, while rxd_enh is then high. when cd is high, rxd and rxd_enh have the same output. miscellaneous analog circuitry voltage references the NCN5192 requires two voltage references, aref and cdref. aref sets the dc operating point of the internal operational amplifiers and is the reference for the rx comparator. if NCN5192 operates at v dd = 3.3 v the on semiconductor lm285d 1.235 v reference is recommended. the level at which cd (carrier detect) becomes active is determined by the dc voltage dif ference (cdref - aref). selecting a voltage difference of 80 mv will set the carrier detect to a nominal 100 mv p-p . bias current resistor the NCN5192 requires a bias current resistor r bias to be connected between cbias and v ss . the bias current controls the operating parameters of the internal operational amplifiers and comparators and should be set to 2.5  a. bias cbias opa aref 2. 5  a r bias pc20101118 .4 figure 10. bias circuit the value of the bias current resistor is determined by the reference voltage aref and the following formula: r bias  aref 2.5  a the recommended bias current resistor is 500 k  when aref is equal to 1.235 v. oscillator the clock signal used by NCN5192 can either be 460.8 khz, 921.6 khz or 1.8432 mhz. this can be provided by an external clock or a resonator or crystal connected to the internal oscillator.
NCN5192 http://onsemi.com 10 internal oscillator option the oscillator cell will function with a 460.8 khz, 921.6 khz or 1.8432 mhz crystal or ceramic resonator. a parallel resonant ceramic resonator can be connected between xin and xout. figure 11 illustrates the crystal option for clock generation using a 460.8 khz ( 1% tolerance) parallel resonant crystal and two tuning capacitors c x . the actual values of the capacitors may depend on the recommendations of the manufacturer of the resonator. typically, capacitors in the range of 100 pf to 470 pf are used. additionally, a resistor may be required between xout and the crystal terminal, depending on manufacturer recommendation. the NCN5192 ic uses clk2 as clock signal for the wave shaping and digital logic. this signal must be set 460.8 khz by activating the proper frequency division in the internal register (bit 1 and 2). the clk1 frequency division (bit 3 and 4) can be freely chosen. this programmable clock signal can be used to drive other ics such as a microcontroller and is not used internally in the NCN5192. xout xin c x c x 460.8 khz crystal oscillator pc20101118 . 5 figure 11. crystal oscillator external clock option it may be desirable to use an external clock as shown in figure 12 rather than the internal oscillator. in addition, the NCN5192 consumes less current when an external clock is used. minimum current consumption occurs with the clock connected to xout and xin connected to v ss . xout xin crystal oscillator pc20101118 .6 460.8 khz figure 12. oscillator with external clock reset the NCN5192 modem includes a power on reset block. an external resistor division of the supply voltage is required, and should be tied to pin vpor. this pin is attached to an internal comparator, and is compared to the aref voltage. when this comparator trips, the resetb pin will be pulled low and the ic will reset. after vpor returns to a valid level, the resetb pin will be held low for at least an additional 35 ms (may be longer depending on clock frequency). the resetb pin will also be pulled low when a microcontroller failure is detected. a watchdog will guard microcontroller communication by looking at the kick pin. when the microcontroller fails to provide a periodical pulse on this pin, the watchdog will pull down the resetb pin for 140  s. a rising edge should be provided to the ic at least every 53 ms. a 1.8 khz kick can also be provided internally if bit 5 of the internal register is set. if the watchdog kick is provided internally, the kick pin should be tied to vss. por vpor opa aref kvde 20110408 .1 vdd figure 13. power on reset block figure 14. 8 bit spi frame figure 15. 16 bit spi frame spi communication the spi bus on the NCN5192 is made up of three signals; data, sclk, and cs. the data is either 8 bits or 16 bits. in the case of 8 bits cs will go high for eight clock cycles of sclk and in the case of 16 bits cs will be high for 16 clock cycles of sclk, as can be seen on figures 14 and 15. cs should first go high at least one clock cycle before the other signals change. one clock cycle is 2.17  s at a master
NCN5192 http://onsemi.com 11 clock frequency of 460.8 khz. cs is clocked in at the falling edge of the clk1 clock to detect if the data is for the mode register or the dac. sclk can begin to clock in data serially to the chip on the falling edge of sclk. sclk should have a maximum frequency of 460.8 khz. the format of the data should be either 8 or 16 bits with the most significant bit first. data is shifted into the chip on the falling edge of sclk, and thus for correct operation data should change only on the rising edge of sclk. the first bit shifted in is the msb. if 14 bit dac communication is utilized, then two 0?s should precede the 14 bits, and 16 clock cycles on sclk should occur. once the data is shifted in, cs should go low no sooner than one clock cycle after the last rising edge of sclk. table 9. internal register description bit description 0 (lsb) 0 = dac in 14 ? bit mode 1 = dac in 16 ? bit mode 1 set the crystal divide so that clk2 is 460.8 khz bit 2 bit 1 0 0 crystal/2 0 1 crystal/4 1 0 crystal/1 1 1 crystal/4 2 3 set the crystal divide for clk1 bit 4 bit 3 0 0 crystal/2 0 1 crystal/4 1 0 crystal/1 1 1 crystal/4 4 5 0 = watchdog kick external (pin) 1 = watchdog kick internal (1.8 khz) 6 0 = rtz output format on dac 1 = non rtz output format on dac 7 (msb) 0 = rxd is low when carrier is off 1 = rxd is high when carrier is off setting this bit, changes the function of rxd to the function of rxd_enh internal register the NCN5192 has an 8 bit register to setup its internal operation. an 8 bit spi communication method is used to write to the mode register. if cs goes low after only 8 clock cycles of sclk the mode register will latch in the 8 bits which are shifted into the spi shift register. in table x an explanation of the usage of each bit is given. all bits are set to ?0? at reset. sigma delta dac the NCN5192 modem has an integrated sigma ? delta modulator for use in a current loop slave transmitter. through this dac, an analog value can be set and transmitted across the current loop. for more information on how to create a current loop slave transmitter, see application notes on the on semi website. the dac output will switch between 0 v and the voltage provided to dacref. to achieve maximum accuracy, the dacref voltage should be kept stable, so that power supply variations are not visible in the dac output. the sigma ? delta modulator output can be set through spi frames containing 14 or 16 significant bits. the length of the data frames can be set through bit 0 is the status register. the output of the dac can be set return to zero (rtz) or non ? rtz. this is important when the rise and fall time of the signal are not identical. this will cause a dc offset depending on the number of rising and falling edges. as the output bits of a sigma ? delta modulator are randomly arranged (ie. for the same setting we could get 01110000 or 01010100), the number of edges might vary over time for a non return to zero signal. setting the dac to ?return to zero? forces the output to have a rising and falling edge for each logic ?1? bit, so that no offset from pulse asymmetry can occur. however, this will decrease the range of the modulator to 50% of dacref, as the maximum duty cycle is 50% instead of 100% for nrz. when a clock failure is detected, using an internal oscillator, the dac output will jump to the level set by the jump pin, until the ic is reset or a rising flank is detected on kick. table 10. spi frame format description bits 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 mode register 8 mode register data dac ? 14 bits mode 16 0 0 dac output word dac ? 16 bits mode 16 dac output word
