CP1122A Datasheet | CHIP

Product Brief OPTRANS Series STM-1 Single Chip Add/Drop Multiplexer System device .. OVERVIEW The CP1122A 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 integrated one SDH overhead processor for dual STM-1, one extend interface for dual STM-4s or dual STM-1s, a tributary unit payload processor for 2 STM-1, E1 mapper for asynchronous mapping and demapping of 21 port E1, a 6 X 6 high and low order cross connecter.
