78P2351R - Serial 155M NRZ to CMI Converter

General Description

The 78P2351R is Teridian’s second generation Line Interface Unit (LIU) for 155 Mbit/s electrical SDH interfaces (STM1e).

The device is a single chip solution that includes an integrated Clock & Data Recovery in both the transmit and receive paths for easy, cost efficient NRZ to CMI conversion.

Key Features

  • ITU-T G.703 compliant, adjustable cable driver for 155.52 Mbps CMI-coded coax transmission Integrated adaptive CMI equalizer and CDR in receive path handles over 12.7dB of cable loss LVPECL-compatible system interface with integrated CDR in transmit path for flexible NRZ to CMI conversion Configurable via HW control pins or 4-wire serial port interface Compliant with ANSI T1.105.03-1994;.

78P2351R Serial 155M NRZ to CMI Converter DATA SHEET www.DataSheet4U.com AUGUST 2006 DESCRIPTION The 78P2351R is Teridian’s second generation Line Interface Unit (LIU) for 155 Mbit/s electrical SDH interfaces (STM1e). The device is a single chip solution that includes an integrated Clock & Data Recovery in both the transmit and receive paths for easy, cost efficient NRZ to CMI conversion. The device interfaces to 75Ω coaxial cable through wideband transformers and can handle over 12.7dB of cable loss. By eliminating the needs for synchronous clocks, the small 78P2351R (7x7mm MLF package) is ideal for new STM1e (ES1) Small Form-factor Pluggable (SFP) transceiver modules. FEATURES • • • • • • • • • • • ITU-T G.703 compliant, adjustable cable driver for 155.
