The AD9854ASTZ from Analog Devices is a high-performance Direct Digital Synthesizer (DDS) IC designed for agile, quadrature LO frequency synthesis and programmable clock generation. It features a 300 MHz internal clock rate and dual 12-bit digital-to-analog converters (DACs), enabling precise signal generation.
Key electrical specifications include a 12-bit resolution and a tuning word width of 48 bits, allowing for fine control over frequency and phase. The device operates over a supply voltage range of 3.14V to 3.47V and a temperature range of -40°C to 85°C. It offers excellent dynamic performance with 80 dB SFDR at 100 MHz and low jitter (<25 ps rms in clock generator mode).
This DDS IC supports various modulation schemes including FSK, BPSK, PSK, chirp, and AM. It features simplified control interfaces with both serial (SPI compatible) and parallel programming options. The AD9854ASTZ is housed in an 80-lead LQFP package, suitable for surface mounting.
Applications for the AD9854ASTZ include agile quadrature LO frequency synthesis, programmable clock generators, FM chirp sources for radar and scanning systems, test and measurement equipment, and commercial and amateur RF exciters.
The supply voltage range is 3.14V to 3.47V.
It is available in an 80-LQFP (14x14mm) surface mount package.
-40°C to +85°C.
The RoHS status is listed as ROHS3 Compliant, but this is unverified with low confidence.
