AD9851 is a 180MHz DDS/DAC Synthesizer launched by Analog Devices, with a clock rate of 180MHz, a selectable 6x reference clock multiplier, a 10-bit high-performance DAC and a high-speed comparator, and a 32-bit frequency tuning word
The AD9851 is a highly integrated CMOS device that combines direct‑digital‑synthesis (DDS) technology with an on‑chip 10‑bit DAC and comparator. It can generate a frequency‑/phase‑agile sine wave or a low‑jitter square wave up to 180 MHz clock rate, with optional 6× reference‑clock multiplication.
The device is supplied in an ultra‑small 28‑lead SSOP package, operates over –40 °C to +85 °C, and consumes as little as 555 mW at full 180 MHz operation. Detailed specifications, pin functions, timing characteristics and application notes are provided for designers.
