DS 3102
S ynchronous Ethernet S upport
S tratum 3 T iming Card IC with
General Desc ription
The DS3102 is a low-cost, feature-rich timing IC for
telecom timing cards. With 8 input clocks, the device
directly accepts both line timing from a large number of
line cards and external timing from external DS1/E1
BITS transceivers. The DS3102 continually monitors all
input clocks and performs automatic
hitless reference
switching if the primary reference fails.
The T0 DPLL
complies with the Stratum 3 requirements of GR-1244,
GR-253, and the requirements of G.813 and G.8262.
The highly programmable DS3102 support numerous
input
and output frequencies including rates required
for SONET/SDH, Synchronous Ethernet (1G, 10G,
and 100Mbps), wireless base stations, and CMTS
systems. PLL bandwidths from 0.5mHz to 400Hz are
supported, and a wide variety of PLL characteristics
and device features can be configured to meet the
needs of many different applications.

The DS3102 register set is backward compatible with
Semtech’s ACS8522 timing card IC. The DS3102 has a
different package and pin arrangement than the
ACS8522.
