RC31008B
RC31008B is VersaClock 7 Programmable Jitter Attenuator manufactured by Renesas.
Description
The RC310xx B are high-performance programmable jitter attenuators with network synchronization capabilities. The devices support JEDEC JESD204B/C for converter synchronization, and Sync E for network-based synchronization.
The RC310xx B are ideal for driving converter circuits in wire-line infrastructure, data center equipment, and instrumentation applications.
