Overview
The AD9954YSV from Analog Devices Inc. is a high-performance direct digital synthesizer (DDS) that integrates advanced technology with an internal high-speed, high-performance 14-bit DAC. This device is designed to generate a frequency-agile analog output sinusoidal waveform up to 160 MHz, making it suitable for applications requiring fast frequency hopping and fine tuning of both frequency and phase. The AD9954YSV operates on a 1.8 V power supply and is packaged in a 48-lead TQFP.
