| CP1122 Product Brief OPTRANS Series CP1122_PB_Rev1.0 March, 2005 STM-1 Single Chip Add/Drop Multiplexer System device www..com 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. TEBGA421 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 TEBGA421 -40 ~ 85 EXT_ODA[7:0] EXT_OJ0J1A EXT_ODB[7:0] EXT_IDA[7:0] EXT_IDB[7:0] EXT_OJ0J1B EXT_TCLKA EXT_TCLKB EXT_IJ0J1A EXT_IJ0J1B EXT_OPLA EXT_OPLB EXT_IPLA EXT_IPLB OCFP OCTMF ICTMF ICFP TELEMODE EXT (Extend Interface) 2 8,12 E1_TDATA[0..20] Drop A Drop B E1_TCLK[0..20] SCLK2 E1_RDATA[0..20] 16 17 2 8,12 0,4 2 RSOH_CLK RSOH_FP RSOH TSOH_CLK TSOH_FP TSOH TUPP (TU Payload Processor) 2 LINE_RPOSA/B LINE_RNEGA/B MAPPER (21 E1 Mapper) Add A Add B HLX SOP (SDH Overhead Processor) 2 16 17 (6x6 High Order and Low Order Cross Connect) RCLKA RCLKB E1_RCLK[0..20] 0,4 LINE_TPOSA/B LINE_TNEGA/B MOTO CSN WRN/RWS RDN/DSN ADD[14:0] DATA[15:0] INT RDY/TAN RESET MP (Microprocessor Interface) SCLK78 SCLK19 GSCLK Copyright (c)2005 Chiphomer Technology Limited Page 1 of 1 CP1122 Product Brief OPTRANS Series CP1122_PB_Rev1.0 March, 2005 STM-1 Single Chip Add/Drop Multiplexer System device www..com Integrated 21 channels E1 mapper for asynchronous mapping and de-mapping to/from a STM-1 with re-timing support on eight channels. The output jitter of 2M data (either mapping jitter or combined jitter) is compliant with G.783 (2000/10) Supports 1+1 low order path protection.
