High performance programmable clock generators for computing, data communication and industrial applications

Renesas RC210xxA (RC21012A, RC21008A and RC21005A) is a high performance programmable clock generator for computing, data communication and industrial applications.

The RC210xxA is a compact, fully integrated low-power, high-performance frequency synthesizer that delivers excellent phase jitter for reference clocks in PCI Express® and Ethernet, while covering a wide output frequency range of up to 650 MHz. It can provide a low-phase jitter non-spread spectrum clock for Ethernet and storage applications at the same time as a spread spectrum PCIe Gen6 clock.
