The model STC3500 IC is an integrated single chip solution for the synchronous timing source in SONET/ SDH network elements. It is the same engine as in the SM3 module and is fully compliant with Telcordia GR-1244-CORE, GR-253, ITU-T G.812 type IV and ITU-T-G813 option 1 when used with an applicable oscillator. The STC3500 can operate in free run, locked or hold over mode, and supports master/slave operation with continuous input reference quality monitoring. Features include: good flexibility for design engineers, accepts eight auto frequency detect reference inputs from 8 kHz to 77.76 MHz and one 8 kHz cross reference, and the input reference frequency can be manually selected or automatically detected.
