SEPTEMBER 2006
DESCRIPTION
The 78P2352 is Teridian’s second generation Line
Interface Unit (LIU) for 155 Mbps SDH/SONET
(OC-3, STS-3, or STM-1) and 140 Mbps PDH (E4)
telecom interfaces. The device is a dual channel,
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
78P2352 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)
Multi Service Switches
Digital Microwave Radios
FEATURES
ITU-T G.703 compliant cable driver for 139.264
Mbps
or
155.52
Mbps
CMI-coded
coax
transmission
Integrated adaptive CMI equalizer and CDR in
receive path handles over 12.7dB of cable loss
Serial, LVPECL system interface with integrated
CRU in transmit path for flexible NRZ to CMI
conversion.
4-bit parallel CMOS system interface with
master and slave Tx clock modes.
Selectable LVPECL compatible NRZ media
interface for 155.52 Mbps optical transmission.
Configurable via HW control pins or 4-wire serial
port interface
Compliant with ANSI T1.105.03-1994; ITU-T
G.751, G.813, G.823, G.825, G.958; and
Telcordia GR-253-CORE for jitter performance.
Receiver Loss of Signal (LOS) detection
compatible with ITU-T G.783
Operates from a single 3.3V supply
Standard and thermally enhanced 128-pin
JEDEC LQFP package options
