GENERAL DESCRIPTION
The DS3251 (single), DS3252 (dual), DS3253
(triple), and DS3254 (quad) line interface units (LIUs)
perform the functions necessary for interfacing at the
physical layer to DS3, E3, or STS-1 lines. Each LIU
has independent receive and transmit paths and a
built-in jitter attenuator. An on-chip clock adapter
generates all line-rate clocks from a single input
clock. Control interface options include 8-bit parallel,
SPI, and hardware mode.
APPLICATIONS
SONET/SDH and PDH Multiplexers
Digital Cross-Connects
Access Concentrators
ATM and Frame Relay Equipment
Routers
PBXs
DSLAMs
CSU/DSUs
