SERIAL INTERFACE

The EVAL-AD7173-8SDZ
serial peripheral interface (SPI) to the Blackfin®
on the SDP-B. There are four primary signals: CS , SCLK, and
DIN (all inputs), and one output from the ADC, DOUT/ RDY .
To operate the EVAL-AD7173-8SDZ
disconnect the AD7173-8
header by removing the 0 Ω R9 through R13 links. Use the test
points to connect the signals to an alternative digital capture setup.

POWER SUPPLIES

Power the evaluation board from the ac-to-dc adapter
connected to J4, or from an external bench top supply applied
to J3 or J5. Linear LDOs generate the required voltages from the
applied input voltage (V
bypass the on-board regulators. The regulators used are the 5 V
fixed output voltage and 2.5 V adjustable output voltage
ADP1720 devices, which supply the AVDD1 and AVDD2 rails
to the ADC; the
the ADP7104 (5 V) to supply 5 V for the
board. Each supply is decoupled where it enters the board and
again at each device in accordance with the schematic. Table 3
shows the various power supply configurations available,
including split supply operation.
