DS3105
Line Card Timing IC
General Description
The DS3105 is a low-cost, feature-rich timing IC for
telecom line cards. Typically, the device accepts two
reference clocks from dual redundant system timing
cards. The DS3105 continually monitors both inputs
and performs automatic hitless reference switching if
the primary reference fails. The highly programmable
DS3105
supports
numerous
input
and
output
frequencies
including
frequencies
required
for
SONET/SDH, Synchronous Ethernet (1G, 10G, and
100Mbps),
wireless
base
stations,
and
CMTS
systems. PLL bandwidths from 18Hz 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 DS3105 register set is backward compatible with
Semtech’s ACS8525 line card timing IC. The DS3105
pinout is similar but not identical to the ACS8525.
Applications
SONET/SDH, Synchronous Ethernet, PDH, and
Other Line Cards in WAN Equipment Including
MSPPs, Ethernet Switches, Routers, DSLAMs,
and Wireless Base Stations
