Description
The RC310xxB are high-performance programmable
jitter attenuators with network synchronization
capabilities. The devices support JEDEC
JESD204B/C for converter synchronization, and
SyncE for network-based synchronization.
The RC310xxB are ideal for driving converter circuits
in wire-line infrastructure, data center equipment, and
instrumentation applications.
