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).
