AMCC S3045B SONET/SDH OC-48 to OC-12 DeMux Product Status: Production Release S3045 Product Photo The S3045 SONET/SDH byte interleave chip is a fully integrated STS-12/STM-4 to STS-48/STM-16 Mux/Demux device. The S3045 performs all necessary byte interleave and byte de-interleave functions for multiplexing and de-multiplexing of four STS-12/STM-4 data streams into/from a single STS-48/STM-16 data stream. The S3045 functions in conformance with SONET/SDH transmission standards and is suitable for SONET-based ATM applications. Byte Interleave parity (B1) is calculated and inserted for the transmit path and calculated, compared and inserted for the receive path. Optional frame synchronous scrambling and descrambling are performed, and an STS-12/STM-4 framing signal is provided to the STS-12/STM-4 interface processors to allow synchronization of the receive STS-12/STM-4 data streams. * Complies with Bellcore and ITU-T specifications * Supports STS-12/STM-4 to STS-48/STM-16 Mux/Demux functions * 8-bit LVDS data path for STS-48/STM-16 data * 8-bit LVTTL data path with parity for each STS-12/STM-4 data stream * Optionally calculates even or odd parity over parallel data bus or data and frame pulse * Compatible with AMCC S3041/S3042 Mux/Demux chipset * Compatible with PMC PM5355 User Network Interface device and PMC PM5312 STTX * Optionally calculates and inserts Byte Interleaved Parity (B1) * Optionally compares B1 Byte Interleave Parity on the receive side. Generates and inserts B1 Error indications (B1ERR) * Optionally calculates and inserts M1 Bytes, and recalculates and inserts the B2 parity bytes due to the M1 insertions * Optionally inserts section-trace bytes (J0/Z0) in the transmit path * Out of Frame (OOF) monitor and alarm indication * Loss of Signal (LOS) monitor and alarm indication * Squelch Mode: Provides downstream clock during Clock Recovery Failure * Receive J0 Frame Pulse (J0FP) indicator * Performs optional Frame synchronous scrambling and descrambling * Provides synchronization signal to STS-12/ STM-4 Network Interface Processors * SONET/SDH-based transmission systems * Fiber optic test equipment (We do not proofread any ads submitted by members) |
