Product Introduction

Overview

The AD9956YCPZ from Analog Devices Inc. is a high-performance Direct Digital Synthesis (DDS) and Phase-Locked Loop (PLL) synthesizer. This device is designed to provide fast frequency hopping and fine tuning resolution, making it ideal for applications requiring agile and precise frequency synthesis. The AD9956YCPZ integrates advanced DDS technology with a high-speed, high-performance 14-bit DAC and an advanced phase frequency detector/charge pump combination. This allows for the synthesis of digitally programmable, frequency-agile analog output sinusoidal waveforms up to 2.7 GHz when used with an external VCO. The device operates over an extended temperature range of −40°C to +125°C, making it suitable for various environments, including automotive applications.
