hv2802/hv2902 ds20005449a-page 14 ? 2015 microchip technology inc. 4.0 detailed description and application information the high-voltage analog switches are used for multiplexing a piezoelectric transducer array in a probe to multiple channel transmitters (tx) arrays in a medical ultrasound system. figure 4-1 shows a typical medical ultrasound image system comprising 64-channels of transmit pulsers, 64-channels of receivers (lna and adc) and 64-channels of t/r switches connecting to 192 elements of an ultrasound transducer probe via a high-voltage analog switch array. figure 4-1: typical medical ultrasound imaging system. the hv2802/hv2902 devices are comprised of two main circuitries: ? a low-power cmos digital serial interface powered by v dd to control the high-voltage analog switches ? high-voltage bilateral analog switch. high-voltage supplies v pp and v nn are needed by the high-voltage level translation circuitry to control the states of the output high-voltage analog switches. in addition, each high-voltage analog switch can be independently controlled because each switch is controlled via a corresponding latch. a 32-bit shift register and 32 latches allow the user to serially load data into the registers, and after completion, to load the data onto the latches that control the states of the high-voltage analog switches. the hv2802/hv2902 have a digital serial interface consisting of logic signals, data in (d in ), clock (clk), data out (d out ), latch enable (le ) and clear (clr). the digital circuits are supplied by v dd and either a 3.3v or a 5v logic can be used. with a v dd = 5v supply, the serial clock frequency can operate up to 20 mhz. the data is shifted into the shift registers on the rising edge (low-to-high transition) of the clock. the switch configuration bit of sw31 is shifted in first and the switch configuration bit of sw0 is shifted in last. to avoid clock feedthrough, the latch enable input (le ) should remain high while the 32-bit data-in signal is shifted into the 32-bit register. after the valid 32-bit data complete shifting into the shift registers, the high-to-low transition of the le signal transfers the contents of the shift register into the latches. finally, setting the le high again allows all the latches to keep the current state, while new data can now be shifted into the shift registers without upsetting the latches. it is recommended to change all the latch states at the same time through this method to avoid possible clock feedthrough noise. see figure 4-2 for details. adc adc adc fpga ctrl logic video cpu memory tx rx t/r switch t/r switch rx tx tx rx t/r switch ch64 ch2 ch1 pzt array hv 2xxx sw array tx / rx array e1 e65 e192 e128 e129 e2 e66 e130 e64
? 2015 microchip technology inc. ds20005449a-page 15 hv2802/hv2902 figure 4-2: latch enable timing waveforms. when the clr input is set high, all 32 latches are cleared of the data. consequently, all the high-voltage switches are set to off state. however, the clr signal does not affect the contents of the shift register, so the shift register can operate independently of the clr signal. hence, after the clr input is set low, the shift register would still retain the previous data. the serial input interface of the hv2802/hv2902 allows multiple devices to daisy-chain together. in this configuration, d out of a hv2802/hv2902 device is connected to the d in of the subsequent device, and so forth. the last d out of the daisy-chained hv2802/hv2902 can either be floating or fed back to an fpga to check the previously stored shift register data. to control all the high-voltage analog switch states in daisy-chained n devices, n times 32 clocks and n times 32 bits of data are shifted into shift registers, while le remains high and clr remains low. after all n times 32 bits of data finish shifting in, the high-to-low transition of the le transfers the data from all n times 32-bit shift registers to n times 32 latches simultaneously. consequently, all n times 32 high-voltage analog switches change states simultaneously. it is recommended that 0.1 uf ceramic decoupling capacitors, with the appropriate voltage ratings, be connected between gnd and the other supplies (v dd , v pp and v nn ). these decoupling capacitors should be placed as close as possible to the device. the hv2802/hv2902 devices do not have a specific power up/down sequence. during the power up/down period, all the analog switch inputs should be within the v pp and v nn range or floating. the rise time and fall time of the power supplies, v dd , v pp and v nn , should be greater than 1 ms. violating the rise time or fall time requirement on the power supplies may cause malfunction such as latch-up or even permanent damage of the device. the hv2902 device has 35 k ? integrated bleed resisters connected from all the analog switch terminals a and b to rgnd. these bleed resisters eliminate voltage build-up on capacitive loads such as piezoelectric transducers. the hv2802 device does not have integrated bleed resistors. d in le clk t wle t sd t h t su t do d out d n 31 d n 30 d n 29 d n 1 d n 0 d n-1 31 d n-1 30 d n-1 29 d n-1 1 d n-1 0 d n 31 *the previous data input in the shift register are shifted out
