GENERAL DESCRIPTION
When paired with an external TCXO or OCXO, the
DS3100
is
a
complete
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 3
and 3E requirements of GR1244, GR-253, and the
requirements of G.812 Type III and G.813. 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.
central
timing
and
The DS3100 registers and I/O pins are backward
compatible with Semtech’s ACS8520 and ACS8530
timing card ICs.
