DS3100 Stratum 2/3E/3 Timing Card IC Data Sheet
●General Description
■When paired with an external TCXO or OCXO,the DS3100 is a complete 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 complies with the Stratum 2,3E,3,4E and 4 requirements of GR1244,GR-253,G.812 Types I–IV,G.813 and G.8262.From the output of the core DPLLs,a wide variety of output clock frequencies and frame pulses can be produced simultaneously on the 11 output clock pins.Two DS3100 devices can be configured in a master/slave arrangement for timing card equipment protection.
■The DS3100 registers and I/O pins are backward compatible with Semtech’s ACS8520 and ACS8530 timing card ICs.
