The SPI port should not be active during periods when the full
dynamic performance of the converter is required. Because the
SCLK signal, the CSB signal, and the SDIO signal are typically
asynchronous to the ADC clock, noise from these signals can
degrade converter performance. If the on-board SPI bus is used for
other devices, it may be necessary to provide buffers between this
bus and the AD9269 to prevent these signals from transitioning
at the converter inputs during critical sampling periods.
SDIO/DCS and SCLK/DFS serve a dual function when the
SPI interface is not being used. When the pins are strapped to
DRVDD or ground during device power-on, they are associated
with a specific function. The Digital Outputs section describes
the strappable functions supported on the AD9269.
CONFIGURATION WITHOUT THE SPI
In applications that do not interface to the SPI control registers,
the SDIO/DCS pin, the SCLK/DFS pin, the OEB pin, and the
PDWN pin serve as standalone CMOS-compatible control pins.
When the device is powered up, it is assumed that the user intends
to use the pins as static control lines for the duty cycle stabilizer,
output data format, output enable, and power-down feature con-
trol. In this mode, connect the CSB chip select to DRVDD,
which disables the serial port interface.

SPI ACCESSIBLE FEATURES
Table 16 provides a brief description of the general features that
are accessible via the SPI. These features are described in detail
in the AN-877 Application Note, Interfacing to High Speed ADCs
via SPI. The AD9269 part-specific features are described in
detail in Table 17.
