Applications
The SCG6500NT is designed for use as a reference input for
OC-192 Framers and SERDES. It generates less than 1 psRMS
jitter over the OC-192 bandwidth.
SCG6500NT is well suited for use in line cards, service
termination cards and similar functions to provide reliable reference,
phase locked, synchronization for TDM, PDH, SONET, and SDH
network equipment. The SCG6500NT provides a jitter filtered,
wander following output signal synchronized to a superior Stratum
or peer input reference signal.
