GENERAL DESCRIPTION

The AD9954 is a direct digital synthesizer (DDS) that uses

advanced technology, coupled with an internal high speed, high

performance DAC to form a complete, digitally programmable,

high frequency synthesizer capable of generating a frequency-

agile analog output sinusoidal waveform at up to 160 MHz.

The AD9954 enables fast frequency hopping coupled with fine

tuning of both frequency (0.01 Hz or better) and phase (0.022°

granularity).

The AD9954 is programmed via a high speed serial I/O port.

The device includes static RAM to support flexible frequency

sweep capability in several modes, plus a user-defined linear

sweep mode of operation. Also included is an on-chip high

speed comparator for applications requiring a square wave

output. An on-chip oscillator and PLL circuitry provide users

with multiple approaches to generate the device’s system clock.

The AD9954 is specified to operate over the extended industrial

temperature range (see Table 2).
