VersaClock®7 Programmable Clock Generator

Renesas' RC210xxA (RC21012A, RC21008A, and RC21005A) are high-performance programmable clock generators for computing, data communications, and industrial applications.

The RC210xxA is a small-form-factor, fully integrated, low-power, high-performance frequency synthesizer providing excellent phase jitter on reference clocks for PCI Express® and Ethernet while covering a wide range of output frequencies up to 650 MHz. It can simultaneously provide low-phase jitter non-spreading clocks for Ethernet and storage applications while providing spread-spectrum PCIe Gen6 clocks.
