AD9854 is a 300MHz single-chip DDS chip produced by Analog Devices. It has a 300MHz internal clock, provides 12-bit control DAC and 14-bit phase offset/modulation, supports FSK/BPSK/HOLD and other data input formats, and supports both serial and parallel programming.
The AD9854 is a highly integrated CMOS DDS device offering a 300 MHz internal clock, 12‑bit output DACs and programmable frequency, phase and amplitude control. It supports multiple programming interfaces (SPI, parallel, 2‑wire/3‑wire) and provides extensive clock‑generation and quadrature synthesis capabilities.
The document provides detailed specifications, pin descriptions, functional block diagrams, ordering information and mechanical dimensions for the 80‑lead LQFP package, along with application examples such as agile LO synthesis, radar chirp sources and RF exciters.
