Status

Active: In Production.

Description

The 78P2351 is Teridian’s second generation line interface unit (LIU) for 155Mbps (OC-3, STS-3, or STM-1) and 140Mbps 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 75Ω 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.
