AD9057

REV. B
T he power-down function of the AD9057 can be exercised
through a board jumper connection. Connect E7 to E9 (+5 V to
PWRDN) for power-down operation. For normal operation,
connect E8 to E9 (ground to PWRDN).
T he encode signal source should be T T L/CMOS compatible
and capable of driving a 50
termination (R7). T he digital
outputs of the AD9057 are buffered through latches on the
evaluation board (U3) and are available for the user at connec-
tor Pins 30–37. Latch timing is derived from the ADC EN-
CODE clock and a digital clocking signal is provided for the
board user at connector Pins 2 and 21.
An onboard reconstruction digital-to-analog converter is
available for quick evaluations of ADC performance using an

oscilloscope or spectrum analyzer. T he DAC converts the
ADC’s digital outputs to an analog signal for examination at
the DAC OUT connector. T he DAC is clocked at the ADC
ENCODE frequency. T he AD9760 is a 10-bit/100 MSPS single
+5 V supply DAC. T he reconstruction signal facilitates quick
system troubleshooting or confirmation of ADC functionality
without requiring external digital memory, timing, or display
interfaces. T he DAC can be used for limited dynamic testing,
but customers should note that test results will be based on the
combined performance of the ADC and DAC (the best ADC
performance will be recognized by evaluating the digital outputs
of the ADC directly).
