GENERAL DESCRIPTION
The DDS acts as a high resolution frequency divider with the
REF_CLK as the input and the DAC providing the output. The
REF_CLK input can be driven directly or used in combination
with an integrated REF_CLK multiplier (PLL). The REF_CLK
input also features an oscillator circuit to support an external
crystal as the REF_CLK source. The crystal can be used in
combination with the REF_CLK multiplier.
The AD9911 I/O port offers multiple configurations to provide
significant flexibility. The I/O port offers an SPI-compatible
mode of operation that is virtually identical to the SPI operation
found in earlier Analog Devices DDS products.

Flexibility is provided by four data pins (Pin SDIO_0,
Pin SDIO_1, Pin SDIO_2, and Pin SDIO_3) that allow four
programmable modes of I/O operation.
The DAC output is supply referenced and must be terminated
into AVDD by a resistor and an AVDD center-tapped trans-
former. The DAC has its own programmable reference to enable
different full-scale currents.
The DDS core (the AVDD pins and the DVDD pins) is powered
by a 1.8 V supply. The digital I/O interface (SPI) operates at
3.3 V and requires that the Pin DVDD_I/O (Pin 49) be
connected to 3.3 V.
