DS3102
Stratum 3 Timing Card IC with
Synchronous Ethernet Support
General Description
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. Two DS3102
devices
can
be
configured
in
a
master/slave
arrangement for timing card equipment protection.
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.
Applications
SONET/SDH Equipment Clocks (SECs)
Synchronous Ethernet Equipment Clocks (EECs)
Timing Card IC in WAN Equipment Including MSPPs,
Ethernet Switches, Routers, DSLAMs, and
Wireless Base Stations
