DESCRIPTION
The 78P2351 is Teridian’s second generation Line
Interface Unit (LIU) for 155 Mbps (OC-3, STS-3, or
STM-1) and 140 Mbps PDH (E4) telecom interfaces.
The device is a single chip solution that includes an
integrated CDR in the transmit path for flexible NRZ
to CMI conversion.
The device can interface to 75
coaxial cable using
CMI coding or directly to a fiber optics transceiver
module using NRZ coding.
The 78P2351 is
compliant with all respective ANSI, ITU-T, and
Telcordia standards for jitter tolerance, generation,
and transfer.
APPLICATIONS
Central Office Interconnects
DSLAMs
Add Drop Multiplexers (ADMs)
PDH/SDH test equipment
Multi Service Switches
Digital Microwave Radios
