PRODUCT OVERVIEW
The AD9956 is Analog Devices’ newest AgileRF synthesizer.
The device is comprised of DDS and PLL circuitry. The DDS
features a 14-bit DAC operating at up to 400 MSPS and a 48-bit
frequency tuning word (FTW). The PLL circuitry includes a
phase frequency detector with scaleable 200 MHz inputs
(divider inputs operate up to 655 MHz) and digital control over
the charge pump current. The device also includes a 655 MHz
CML-mode PECL-compliant driver with programmable slew
rates. The AD9956 uses advanced DDS technology, an internal
high speed, high performance DAC, and an advanced phase
frequency detector/charge pump combination, which, when
used with an external VCO, enables the synthesis of digitally
programmable, frequency-agile analog output sinusoidal wave-
forms up to 2.7 GHz. The AD9956 is designed to provide fast
frequency hopping and fine tuning resolution (48-bit frequency
tuning word). Information is loaded into the AD9956 via a
serial I/O port that has a device write-speed of 25 Mb/s. The
AD9956 DDS block also supports a user-defined linear sweep
mode of operation.
The AD9956 is specified to operate over the extended
automotive range of 40°C to +125°C.
