78P2351 OC-3/STM-1/STS-3/E4 Single Channel Line Interface Transceiver

The 78P2351 is TDK's second generation Line Interface Unit(LIU) for 155 Mbit/s SDH/SONET (OC-3, STS-3, or STM-1) and 140 Mbit/s PDH (E4) applications.

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 module using NRZ coding. The 78P2351 is compliant with all respective ANSI, ITU-T, and Telcordia standards for jitter tolerance, generation, and transfer.
