Description
The RC31xxxB (RC31008B and RC31012B) are small form factor, fully integrated, low-power, high-performance jitter attenuators with network synchronization capabilities. The family supports JEDEC JESD204B/C for converter synchronization and SyncE for network-based synchronization. The RC31xxxB are ideal for driving converter circuits in wireless and wireline infrastructure, data center equipment, and instrumentation applications. The devices are members of Renesas' high-performance VersaClock® 7 family
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.
