STC3500 Description
The STC3500 is an integrated single chip solution for the Synchronous Timing Source in SONET/SDH network elements. The device generates four synchronous clocks, including BITS, and is fully pliant with Telcordia GR-1244-CORE, GR-253-CORE and ITU-T G.812/G.813. The STC3500 can operate in Free Run, locked or Hold Over mode.
