Overview

The RC21xxxB (RC21012B and RC21008B) is a member of Renesas's VersaClock® 7 programmable clock generator family. It is intended for high-performance computers, data communications, and industrial applications, designed to be placed immediately adjacent to a PHY, switch, ASIC or FPGA that requires several reference clocks with jitter performance 150fs typical RMS.

Up to 27 configurations reusable across multiple designs may be stored in on-chip One-Time Programmable (OTP) memory or external I2C EEPROM. Redundant input is available for backup and used as a reference clock where needed.
