Product Overview
The CDCM7005RGZT from Texas Instruments is a high-performance clock jitter cleaner and frequency synthesizer designed for demanding applications requiring low phase noise and precise clock generation. It integrates a phase-locked loop (PLL) with a voltage-controlled oscillator (VCO) to clean jitter from reference clocks and generate multiple output frequencies. The device operates from a 2.5V or 3.3V supply and is housed in a compact 48-VQFN (7x7 mm) package.
