AD9057
–9–
The power-down function of the AD9057 can be done 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).
The encode signal source should be TTL/CMOS compatible and
capable of driving a 50
W termination (R7). The digital outputs
of the AD9057 are buffered through latches on the evaluation
board (U3) and are available for the user at connector Pins 30
to 37. Latch timing is derived from the ADC encode clock and a
digital clocking signal is provided for the board user at connector
Pins 2 and 21.
An on-board reconstruction digital-to-analog converter is
available for quick evaluations of ADC performance using an
oscilloscope or spectrum analyzer. The DAC converts the ADC’s
digital outputs to an analog signal for examination at the DAC
OUT connector. The DAC is clocked at the ADC encode
frequency. The AD9760 is a 10-bit/100 MSPS single 5 V supply
DAC. The reconstruction signal facilitates quick system trouble-
shooting or confirmation of ADC functionality without requiring
external digital memory, timing, or display interfaces. The 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).
