max3802 detailed description the max3802 has four independent adaptive equaliz- ers (receivers) and four independent drivers. dis- connecting the power pins of unused equalizers and drivers lowers the power consumption of the max3802. equalizer and driver descriptions apply to the four iden- tical sections. cable driver the cable driver accepts differential or single-ended cml input data at rates up to 3.2gbps. the maximum cml output of the driver can be adjusted over a typical range of 445mv to 825mv by changing the value of the r mod_ resistor between 10k ? and 20k ? (resistor con- nected between rmod_ pin and ground). adaptive cable equalizer the adaptive cable equalizer is capable of equalizing differential or single-ended cml input data at rates up to 3.2gbps. it automatically adjusts to attenuation lev- els of 30db at 1.6ghz (due to skin-effect losses in cop- per cable). the equalizer consists of a cml input buffer, a flat-response amplifier, a skin-effect compen- sation amplifier, a current-steering network, a dual power-detector feedback loop, an output limiting ampli- fier, and a cml output buffer (figure 1). general theory of operation the shape of the power spectrum of a random bit stream can be described by the square of the well- known sinc function, where sinc(f) = sin( f)/( f) for f 0. for sufficiently long bit patterns (nonrandom bit stream), sinc 2 (f) is a good approximation. from the shape of the sinc 2 (f) function, the ratio of the power densities at any two frequencies can be estimated. the max3802 adaptive equalizer employs this principle by incorporating a feedback loop that continuously moni- tors the power at high- and low-frequency bands and 3.2gbps quad adaptive cable equalizer with cable driver 8 _______________________________________________________________________________________ max3802 variable attenuator variable attenuator current-steering network flat response amp cml cml cml cml skin- effect comp amp |h(f)| power detector ein_ dout_ 2 2 los_ cable driver |h(f)| f rmod_ r mod_ 2 din_ 2 eout_ limiting amp 600mhz pwr detector 200mhz pwr detector loop filter figure 1. max3802 functional diagram
dynamically adjusts the equalizer to maintain the cor- rect power ratio. cml input and output buffers the input and output buffers are implemented using cml. equivalent circuits are shown in figures 2 and 3. for details on interfacing with cml, refer to maxim application note hfan-01.0, interfacing between cml, pecl, and lvds. flat-response and skin-effect compensation amplifiers the buffered input waveform is fed equally to two amplifiers?he flat-response amplifier and the skin- effect compensation amplifier. the flat-response ampli- fier has a constant gain over the entire frequency range of the device, and the skin-effect compensation amplifi- er has a gain characteristic that approximates the inverse of the skin-effect attenuation in copper cable. the skin-effect attenuation, in db per unit length, is pro- portional to the square root of the frequency. the out- put currents from the amplifiers are supplied to the current-steering network. current-steering network the function of the current-steering network is to com- bine adjustable quantities of the output currents from the flat-response and skin-effect compensation ampli- fiers in order to achieve a desired current ratio. the ratio adjustment is controlled by the dual power-detec- tor feedback loop. the current-steering network is implemented with a pair of variable attenuators that feed into a current-summing node. the variable attenuators are used to attenuate the output currents of the flat-response and skin-effect compensation amplifiers under control of the dual power-detector feedback loop. the outputs of the two attenuators are combined at the summing node and then fed to the output-limiting amplifier and the feed- back loop. dual power-detector feedback loop the outputs of the current-steering network are applied to the inputs of 200mhz and 600mhz power detectors. the outputs of the power detectors are applied to the loop-filter amplifier. this amplifier controls the variable attenuators in the current-steering network. output limiting amplifier the output limiting amplifier amplifies the signal from the current-steering network to achieve the specified output voltage swing. applications information refer to maxim application note hfdn-10.0, equalizing gigabit copper cable links with the max3800 (available at www.maxim-ic.com) for addi- tional application information. selecting r mod the cable driver output amplitude can be adjusted by connecting a resistor (r mod ) with a value from 10k ? to 20k ? between the rmod_ pin and ground. the exact output amplitude of the driver is dependent on several max3802 3.2gbps quad adaptive cable equalizer with cable driver _______________________________________________________________________________________ 9 _in_- _in_+ esd structures v cc 50 ? 50 ? max3802 figure 2. cml input structure esd structures 62.5 ? 62.5 ? _out_- _out_+ v cc max3802 figure 3. cml output structure
max3802 factors. see the typical operating characteristics cable driver output voltage vs. r mod for typical values. cable integrity monitor the cim_ output voltage is directly proportional to the output current of the loop amplifier (which controls the current-steering network; see detailed description ). this is an analog voltage output that indicates the amount of equalization being applied. the amount of equalization (and thus the cim_ output level) is affected by cable type, cable length, signal bandwidth, etc. see the typical operating char- acteristics cim voltage vs. cable length for typical val- ues under specific conditions. loss-of-signal ( los_ ) output loss of signal is indicated by the los_ output. a low level on los_ indicates that the equalizer input power has dropped below a threshold. when there is suffi- cient input voltage to the channel (typically greater than 250mv), los_ is high. the los_ output is suitable for indicating problems with the transmission link caused by, for example, a broken cable or a defective driver. data spectrum for equalizer the max3802 equalizer design requires the data stream be scrambled or coded to provide a rich fre- quency spectrum for the adaptation algorithm. scrambled patterns or coded patterns with scrambled content, such as 64b/66b or sonet prbs, are ideal. some coded patterns, such as 8b/10b, lack low-fre- quency energy and can be nonoptimal, requiring the user to characterize the specific application. in the absence of an input signal (nonstandard application), amplified noise may appear at the output due to the large gain of the device. single-ended operation for single-ended operation of the cable driver or equal- izer, connect the unused input to ground through a series combination of a capacitor (of equal value to other ac-coupling capacitors) and a 50 ? resistor. note that the max3802 is specified for differential operation. layout considerations the max3802? performance can be significantly affected by circuit board layout and design. use good high-frequency design techniques, including minimiz- ing ground inductance and using controlled-imped- ance transmission lines for the high-frequency data signals. power-supply decoupling capacitors should be placed as close as possible to v cc . exposed-pad package the ep on the 68-pin qfn provides a very low thermal resistance path for heat removal from the ic. the pad is the electrical ground on the max3802 and must be sol- dered to the circuit board ground for proper thermal and electrical performance. refer to maxim application note hfan-08.1, thermal considerations for qfn and other exposed-pad packages (available at www.maxim- ic.com) for additional application information. chip information transistor count: 5408 process: bipolar (silicon germanium) 3.2gbps quad adaptive cable equalizer with cable driver 10 ______________________________________________________________________________________ max3802 v ccd 1 rmod1 v cce 1 eout1+ eout1- v cce 1 din1+ din1- v ccd 1 dout1+ dout1- cim1 v cce 1 ein1+ ein1- v cce 1 11 10 9 8 7 6 5 4 3 2 16 15 14 13 12 1 17 los1 ein2- qfn* v cce 2 v cce 2 ein2+ v cce 2 cim2 eout2+ eout2- rmod2 v cce 2 dout2- v ccd 2 v ccd 2 dout2+ din2- 23 22 21 20 19 27 26 25 24 18 29 28 32 31 30 din2+ 34 33 *the exposed pad of the qfn package must be soldered to ground for proper thermal and electrical operation of the max3802. los2 38 39 40 41 42 43 44 45 46 47 dout3+ dout3- v ccd 3 rmod3 v cce 3 eout3+ eout3- v cce 3 cim3 v cce 3 35 36 37 ein3+ ein3- v cce 3 48 v ccd 3 49 50 din3+ din3- 51 los3 58 59 60 61 62 54 55 56 57 63 dout4- top view v ccd 4 rmod4 v cce 4 eout4+ eout4- v cce 4 cim4 v cce 4 ein4+ 52 53 ein4- v cce 4 64 dout4+ 65 66 67 din4+ din4- v ccd 4 68 los4 pin configuration
