| CP1121A Product Brief OPTRANS Series STM-1/4 Single Chip Add/Drop Multiplexer System device www..com OVERVIEW The CP1121A 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-4 or dual STM-1, one extend interface for dual STM-4s or dual STM-1s, a tributary unit payload processor for 8 STM-1, E1 mapper for asynchronous mapping and demapping of 21 port E1, a 18 X 18 high and low order cross connecter. TEBGA421 FEATURES SDH Overhead Processor Dual channel SDH STM-4 or STM-1 Serial LVDS interfaces Dual channel multi-rate CDR macro is integrated High jitter performance complies with ITU-T specification Regenerator and multiplex section overheads are terminated High order AU-4 pointer interpretation and generation VC-4 path overheads termination Full access SOH through external serial interfaces Support path loop-back Support Multiplex Section Protection Switch TUPP TEBGA421 -40 ~ 85 EXT_TCLKA EXT_OJ0J1A EXT_OPLA EXT_TCLKB EXT_OJ0J1B EXT_OPLB EXT_IJ0J1A EXT_IPLA EXT_IJ0J1B EXT_IPLB EXT_ODA[7:0] EXT_ODB[7:0] EXT_IDA[7:0] EXT_IDB[7:0] OCFP OCTMF ICFP ICTMF TELEMODE EXT (Extend Interfaces) 8 E1_TDATA[0..20] E1_TCLK[0..20] SCLK2 E1_RDATA[0..20] E1_RCLK[0..20] 8~15 Drop A Drop B 16 17 8 8~15 0~7 8 RSOH_CLK RSOH_FP RSOH TSOH_CLK TSOH_FP TSOH TUPP (TU Payload Processor) 8 LINE_RPOSA/B LINE_RNEGA/B MAPPER (21 E1 Mapper) HLX SOP (SDH Overhead Processor) (18x18 High Order and Low Order Cross Connect) Add A 16 Add B 17 0~7 RCLKA RCLKB LINE_TPOSA/B LINE_TNEGA/B 8 MOTO CSN WRN/RWS RDN/DSN ADD[14:0] DATA[15:0] INT RDY/TAN MP (Microprocess or Interface) RESET RCKP RCKN RCKC SCLK78 SCLK19 GSCLK Copyright (c)2004 Chiphomer Technology Limited Page 1 of 2 CP1121A Product Brief OPTRANS Series STM-1/4 Single Chip Add/Drop Multiplexer System device www..com Process TU-12/TU-3 Pointer Aligns SDH tributary unit within 8 STM-1.
