Product Overview
The CDCE72010RGCR from Texas Instruments is a high-performance clock jitter cleaner and frequency synthesizer designed for demanding applications requiring ultra-low phase noise and jitter. It integrates a fractional-N phase-locked loop (PLL) with a voltage-controlled oscillator (VCO) and provides up to 10 differential or 20 single-ended clock outputs. The device operates from a 3.3V supply and supports output frequencies up to 1.175 GHz. With an RMS jitter of 0.15 ps (typical, 12 kHz to 20 MHz), it is ideal for clocking high-speed data converters, FPGAs, and communication systems.
