OVERVIEW

The CP1122 is one of the OPTRANS series chips designed by

Chiphomer Technology Limited. It is extended to provide a flexible,

low cost System-on-chip (SOC) solution for fast growing metropolitan

transmission market, especially in Multi-service Transport Platform

(MSTP) and Customer Premises Equipment (CPE) applications. It

integrates one SDH overhead processor for dual STM-1, one extension

interface for dual STM-1, a tributary unit payload processor for 2

STM-1, E1 mapper for asynchronous mapping and demapping of 21 E1

ports, a 6 X 6 high and low order cross connector.

FEATURES

Dual SDH STM-1 serial LVPCEL interfaces

Integrated two-channel CDR macros to interface directly with an

optical module

Fully compliant with ITU-T specifications for Jitter Tolerance,

Transfer and Generation

Regenerator and multiplexer section termination

High order processing for AU-4 pointer interpretation/generation

and POH termination

Full access to SOH through a serial interface.

Integrated MSP processing to support 1+1, 1:n protection

Byte-wide 19.44MHz Extension Telecom Bus

Aligns SDH tributary TU3/TU12 for every TUG3 within 8 STM-1 or bypass
