HARDWARE INTERFACE
The pins described in Table 14 compose the physical interface
between the user’s programming device and the serial port of
the AD9222. The SCLK and CSB pins function as inputs when
using the SPI. The SDIO pin is bidirectional, functioning as an
input during write phases and as an output during readback.
If multiple SDIO pins share a common connection, care should
be taken to ensure that proper V
same load for each AD9222, Figure 83 shows the number of SDIO
pins that can be connected together and the resulting V

This interface is flexible enough to be controlled by either serial
PROMS or PIC mirocontrollers, providing the user with an
alternative method, other than a full SPI controller, to program
the ADC (see the AN-812 Application Note).
If the user chooses not to use the SPI, these dual-function pins
serve their secondary functions when the CSB is strapped to
AVDD during device power-up. See the Theory of Operation
section for details on which pin-strappable functions are
supported on the SPI pins.
