SCS3012
The SCS3012 is an
integrated chip solution for the Stratum 3 Synchronous Timing Source in SONET/SDH
network elements. The device generates four synchronous clocks, including BITS,
and is fully compliant with Telcordia GR-1244-CORE, GR-253 and ITU-T
G.812/G.813.
Designed
specifically for ease of use and application integration, the SCS3012 also
provides industry-leading exceptionally low jitter performance.
