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
STM-1 Single Chip Add/Drop Multiplexer System device
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
