CONFIGURATION WITHOUT THE SPI
In applications that do not interface to the SPI control registers,
the SDIO/DCS pin, the SCLK/DFS pin, the SMI SDO/OEB pin,
and the SMI SCLK/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 control. In this mode, the CSB
chip select should be connected to AVDD, which disables the
serial port interface.

SPI ACCESSIBLE FEATURES
Brief descriptions of the general features available on many
Analog Devices, Inc., high speed ADCs, including the AD9600,
that are accessible via the SPI are included in Table 21. These
features are described in detail in the AN-877 Application Note,
Interfacing to High Speed ADCs via SPI. The AD9600 part-specific
features are described in the Memory Map Register Description
section.
