.. DS3100 Stratum 3/3E Timing Card IC .maxim-ic. GENERAL DESCRIPTION When paired with an external TCXO or OCXO, the DS3100 is a plete central timing and synchronization solution for SONET/SDH network elements. With two multiprotocol BITS/SSU receivers and 14 input clocks, the device directly accepts both external timing and line timing from a large number of line cards. All input clocks are continuously monitored for frequency accuracy and activity. Any two of the input clocks can be selected as the references for the two core DPLLs. The T0 DPLL plies with the Stratum 3 and 3E requirements of GR1244, GR-253, and the requirements of G.812 Type III and G.813....
