notes 1. the ad9411 has a conductive heat slug to help dissipate heat and ensure reliable operation of the device over the full industrial temperature range. the slug is exposed on the bottom of the package and electrically connected to chip ground. it is recommended that no pcb signal traces or vias be located under the package that could come in contact with the conductive slug. attaching the slug to a ground plane will reduce the junction temperature of the device which may be beneficial in high temperature environments. figure 3. tqfp_ep pinout obsolete data sheet ad9411 rev. b | page 9

input frequency at which the spectral power of the fundamental frequency (as determined by the fft analysis) is reduced by 3 db. aperture delay the delay between the 50% point of the rising edge of the clock command and the instant at which the analog input is sampled. aperture uncertainty (jitter) the sample-to-sample variation in aperture delay. crosstalk coupling onto one channel being driven by a low level (C40 dbfs) signal when the adjacent interfering channel is driven by a full- scale signal. differential analog input resistance, differential analog input capacitance, and differential

computed by observing the voltage on a single pin and subtracting the voltage from the other pin, which is 180 out of phase. peak-to-peak differential is computed by rotating the inputs phase 180 and again taking the peak measurement. the difference is then computed between both peak measurements. differential nonlinearity the deviation of any code width from an ideal 1 lsb step. effective number

application notes the ad9411 architecture is optimized for high speed and ease of use. the analog inputs drive an integrated high bandwidth track-and-hold circuit that samples the signal prior to quantiza- tion by the 10-bit core. for ease of use, the part includes an on- board reference and input logic that accepts ttl, cmos, or lvpecl levels. the digital outputs logic levels are lvds (ansi-644) compatible. clock input any high speed a/d converter is extremely sensitive to the quality of the sampling clock provided by the user. a track-and- hold circuit is essentially a mixer, and any noise, distortion, or timing jitter on the clock is combined with the desired signal at the a/d output. for this reason, considerable care has been taken in the design of the clock inputs of the ad9411, and the user is advised to give careful thought to the clock source. th e ad9411 has an internal clock duty cycle stabilization circuit that locks to the rising edge of clk+ and optimizes timing internally. this allows a wide range of input duty cycles at the input without degrading performance. jitter in the rising edge of the input is still of paramount concern and is not reduced by the internal stabilization circuit. the duty cycle control loop does not function for clock rates less than 30 mhz nominally. the time constant associated with the loop should be considered in applications where the clock rate changes dynamically, requiring a wait time of 1.5 s to 5 s after a dynamic clock frequency increase before valid data is available. this circuit is always on and cannot be disabled by the user. the clock inputs are internally biased to 1.5 v (nominal) and support either differential or single-ended signals. for best dynamic performance, a differential signal is recommended. an mc100lvel16 performs well in the circuit to drive the clock inputs, as illustrated in figure 39. note that for this low voltage pecl device, the ac coupling is optional. 04530-a-017

is a differential buffer. for best dynamic performance, impedances at vin+ and vinC should match. the analog input is optimized to provide superior wide- band performance and requires that the analog inputs be driven differentially. snr and sinad performance degrades signifi- cantly if the analog input is driven with a single-ended signal. a wideband transformer, such as mini-circuits adt1-1wt, can provide the differential analog inputs for applications that require a single-ended-to-differential conversion. both analog inputs are self-biased by an on-chip resistor divider to a nominal 2.8 v (refer to the equivalent circuits section). note that the input common-mode can be overdriven by approximately +/?150 mv around the self-bias point, as shown in figure 42. special care was taken in the design of the analog input section of the ad9411 to prevent damage and corruption of data when the input is overdriven. the nominal differential input range is approximately 1.5 v p-p ~ (768 mv 2). note that the best performance is achieved with s5 = 0 (full-scale = 1.5). see figure 40 and figure 41. 04530-0-041 s5 = gnd vin+ 2.8v 768mv 2.8v vin? digitalout = all 1s digitalout = all 0s

= 0) lvds outputs the off-chip drivers provide lvds compatible output levels. a 3.74 k rset resistor placed at pin 7 (lvdsbias) to ground sets the lvds output current. the rset resistor current is ratioed on-chip, setting the output current at each output equal to a nominal 3.5 ma (11 irset). a 100 differential termi- nation resistor placed at the lvds receiver inputs results in a nominal 350 mv swing at the receiver. lvds mode facilitates interfacing with lvds receivers in custom asics and fpgas that have lvds capability for superior switching performance in noisy environments. single point-to-point network topologies are recommended with a 100 termination resistor as close to the receiver as possible. it is recommended to keep the trace lengths < 4 inches and to keep differential output trace lengths as equal as possible. clock outputs (dco+, dcoC) the input clock is buffered on-chip and available off-chip at dco+ and dcoC. these clocks can facilitate latching off-chip, providing a low skew clocking solution (see figure 2). the on- chip clock buffers should not drive more than 5 pf of capacitance to limit switching transient effects on performance. the output clocks are lvds signals requiring 100 differential termination at receiver. voltage reference a stable and accurate 1.23 v voltage reference is built into the ad9411 (vref). the analog input full-scale range is linearly proportional to the voltage at vref. note that an external reference can be used by connecting the sense pin to vdd (disabling internal reference) and driving vref with the external reference source. no appreciable degradation in performance occurs when vref is adjusted 5%. a 0.1 f capacitor to ground is recommended at the vref pin in internal and external reference applications.

43. using an external reference noise power ratio testing (npr) npr is a test that is commonly used to characterize the return path of cable systems where the signals are typically qam sig- nals with a noise-like frequency spectrum. npr performance of the ad9411 was characterized in the lab yielding an effective npr = 51.2 db at an analog input of 18 mhz. this agrees with a theoretical maximum npr of 51.6 db for a 10-bit adc at 13 db backoff. the rms noise power of the signal inside the notch is compared with the rms noise level outside the notch using an fft. this test requires sufficiently long record lengths to guarantee a large number of samples inside the notch. a high- order band-stop filter that provides the required notch depth for testing is also needed. obsolete ad9411 data

ad9411 in lvds mode. it requires a clock source, an analog input signal, and a 3.3 v power supply. the clock source is buffered on the board to provide the clocks for the adc, latches, and a data-ready signal. the digital outputs and output clocks are available at a 40-pin connector, p23. the board has several different modes of operation and is shipped in the following configurations: ? offset binary ? internal voltage reference ? full-scale adjust = low power connector power is supplied to the board via a detachable 12-lead power strip (three 4-pin blocks). table 8. power connector,

optional external reference input 1 avdd, drvdd, and vdl are the min imum required po wer connections. 2 lvel16 clock buffer can be powered from avdd or vclk at e47 jumper. analog inputs the evaluation board accepts a 1.3 v p-p analog input signal centered at ground at smb connector j4. this signal is terminated to ground through 50 by r16. the input can be alternatively terminated at the t1 transformer secondary by r13 and r14. t1 is a wideband rf transformer that provides a single-ended-to-differential conversion, allowing the adc to be driven differentially, which minimizes even-order harmonics. an optional second transformer, t2, can be placed following t1 if desired. this provides some performance advantage (~1 db to 2 db) for high analog input frequencies (>100 mhz). if t2 is placed, cut the two shorting traces at the pads. the analog signal can be low-pass filtered by r41, c12 and r42, c13 at the adc input. the footprint for transformer t2 can be modified to accept a wideband differential amplifier (ad8351) for low frequency applications where gain is required. see the pcb schematic for more information. gain full scale is set at e17Ce19, e17Ce18 sets s5 low, full scale = 1.5 v differential; e17Ce19 sets s5 high, full scale = 0.75 v differential. best performance is obtained at 1.5 v full scale. clock the clock input is terminated to ground through 50 resistor at smb connector j5. the input is ac-coupled to a high speed differential receiver (lvel16) that provides the required low jitter, fast edge rates needed for optimum performance. j5 input should be > 0.5 v p-p. power to the lvel16 is set at jumper e47. e47Ce45 powers the buffer from avdd; e47Ce46 powers the buffer from vclk/v_xtal. voltage reference the ad9411 has an internal 1.23 v voltage reference. the adc uses the internal reference as the default when jumpers e24Ce27 and e25Ce26 are left open. the full scale can be increased by placing an optional resistor (r3). the required value varies with the process and needs to be tuned for the specific application. full scale can similarly be reduced by placing r4; tuning is required here as well. an external reference can be used by shorting the sense pin to 3.3 v (place jumper e26Ce25). jumper e27Ce24 connects the adc vref pin to the ext_vref pin at the power connector. data format select data format select (dfs) sets the output data format of the adc. setting dfs (e1Ce2) low sets the output format to be offset binary; setting dfs high (e1Ce3) sets the output to twos complement. data outputs the adc lvds digital outputs are routed directly to the connector at the card edge. resistor pads placed at the output connector allow for termination if the connector receiving logic lack the differential termination for the data bits and dco. each output trace pair should be terminated differentially at the far end of the line with a single 100 ohm resistor. clock xtal an optional xtal oscillator can be placed on the board to serve as a clock source for the pcb. power to the xtal is through the vclk/vxtal pin at the power connector. if an oscillator is used, ensure proper termination for best results. the board
