AD9951YSV

Overview

The AD9951YSV is a direct digital synthesizer (DDS) featuring an integrated 14-bit DAC operating at up to 400 MSPS. It generates frequency-agile analog output sinusoidal waveforms up to 200 MHz using advanced DDS technology and a 32-bit tuning word for fine resolution. The device supports serial I/O control, software/hardware power-down modes, and a PLL REFCLK multiplier ranging from 4× to 20×. It operates on a 1.8 V supply with 5 V tolerant inputs and functions within an extended industrial temperature range of –40°C to +105°C.
