78P2352 - Dual Channel OC-3/ STM1-E/ E4 LIU

General 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.

Key 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 transmissi.

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 75Ω coaxial cable using CMI coding or directly to a fiber optics transceiver module using NRZ coding. The 78P2352 is compliant with all respective ANSI, ITUT, and Telcordia standards for jitter tolerance, generation, and transfer.
