RC22112A FemtoClock™ Clock Generator

Renesas Electronics RC22112A FemtoClock™ Clock Generator is a fully integrated, low-power, high-performance clock generator. This generator features PCIe Gen 1-6 CC, SRIS, SRNS support, and less than 100fs-RMS low jitter. The RC22112A generator supports 1MHz I²C, 400kHz SMBus, or 50MHz SPI serial port, up to six fractional output dividers, and 12 integer output dividers. This clock generator provides reference clocks for high-speed serial links up to 28Gbps Ethernet in fabric cards in data center equipment. Typical applications include switches/routers, clock generation for 10Gbps/25Gbps/40Gbps/100Gbps/200Gbps/400Gbps Ethernet PHYs in switch fabric cards, medical imaging, and professional audio and video.
