Product Overview
The CDCE937PWR from Texas Instruments is a high-performance, modular clock synthesizer designed for a wide range of applications. It features three independent PLLs, each capable of generating up to seven different output frequencies from a single input reference. The device operates from a 1.8V core supply and supports output frequencies up to 230 MHz. With its low jitter and programmable spread spectrum, the CDCE937PWR is ideal for reducing EMI in high-speed digital systems.
