The AD9854AST is a CMOS 300 MSPS quadrature complete direct digital synthesizer (DDS) from Analog Devices. It operates with a 300 MHz internal clock rate and provides excellent dynamic performance with 80 dB SFDR at 100 MHz output. The device integrates dual 12-bit digital-to-analog converters (DACs) and a 48-bit tuning word width for fine frequency resolution. It supports multiple modulation schemes including FSK, BPSK, PSK, chirp, and AM operation.
Key electrical specifications include a supply voltage range of 3.14V to 3.47V and an operating temperature range of -40°C to 85°C. The DDS includes a programmable 4x to 20x reference clock multiplier, dual 48-bit frequency registers, dual 14-bit phase offset registers, and a 12-bit amplitude modulation function. It also features an ultrahigh-speed comparator with 3 ps rms jitter for clock generation applications.
The AD9854AST is housed in an 80-lead LQFP package (14x14mm) with surface mount mounting. Designed for agile LO frequency synthesis, programmable clock generators, FM chirp sources for radar, test and measurement equipment, and RF exciters.
