DESCRIPTION  
FEATURES  
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 75coaxial  
cable using CMI coding or directly to a fiber optics  
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.  
transceiver module using NRZ coding.  
The  
4-bit parallel CMOS system interface with  
master and slave Tx clock modes.  
78P2352 is compliant with all respective ANSI, ITU-  
T, and Telcordia standards for jitter tolerance,  
generation, and transfer.  
Selectable LVPECL compatible NRZ media  
interface for 155.52 Mbps optical transmission.  
Configurable via HW control pins or 4-wire serial  
port interface  
APPLICATIONS  
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  
Central Office Interconnects  
DSLAMs  
Add Drop Multiplexers (ADMs)  
Multi Service Switches  
Digital Microwave Radios  
Operates from a single 3.3V supply  
Standard and thermally enhanced 128-pin
