PM5347 S/UNI-155-PL US
155 Mb/s SATURN User Network Interface for WANs
FEATURES
· Monolithic SATURNTM-compatible Asynchronous Transfer Mode (ATM) network interface. · Implements the ATM transmission convergence (TC) sublayer for ATM according to ATM Forum specifications and ITU-T recommendations using the SONET/SDH 155.52 Mb/s format. Also implements ATM Forum specified "Mid-range PHY" rates of 51.52, 25.92 and 12.96 Mb/s. · Includes on-chip clock recovery and clock synthesis at all rates. Clocking can be bypassed for use with external clock sources. Operates in master or slave (loop timed) timing modes. · Provides TTL-compatible inputs and outputs. Provides differential pseudoECL-compatible serial line side inputs. · Supports Fiber Optic, Unshielded Twisted Pair and Shielded interfaces. · Processes all SONET/SDH UNI overhead. · Provides access to section and line datalinks and all additional transport and path overhead to allow additional external processing for full SONET/ SDH Network-Node Interface (NNI) compliance. · Provides synchronous 8-bit or 16-bit SCI-PHYTM system side interface with 4-cell deep FIFO buffers in transmit and receive paths with parity support. · Inserts and extracts ATM payloads using cell delineation. · Provides a generic 8-bit microprocessor bus interface for configuration, control, and status monitoring. · Software-compatible with the PM5345 S/UNI-155TM, PM5346 S/UNI-155LITETM and the PM5355 S/UNI-622TM. · Provides a standard 5-signal P1149.1 JTAG test port for boundary scan board test purposes. · Low power, +5 V CMOS technology. · Packaged in a 208 pin (28mm x 28mm) PQFP with 0.5mm pin pitch. · Industrial temperature range operation (-40°C to +85°C). · Counts received cells written into the receive FIFO, received HCS errored cells that are discarded, and received HCS errored cells that are corrected and passed through the receive FIFO.
PMC-930909 (R7)
TRANSMIT SECTION
· Counts transmit cells read from the transmit FIFO. · Inserts a register programmable path signal label (C2). · Inserts path B3, path FEBE indications, line B2, line FEBE indications, and section B1 to allow performance monitoring at the far end. · Optionally inserts the 16- or 64-byte section trace (J0) sequence and the 16 or 64 byte path trace (J1) sequence from internal register banks. · Optionally inserts an externally generated section user channel (F1), order wire channels (E1, E2) and the DCC channels (D1-D3 and D4-D12) via serial interfaces. · Optionally inserts path AIS, path RDI, line AIS, and line RDI. · Optionally inserts register programmable APS (K1, K2) and synchronization status (Z1) bytes.
· Extracts the 16- or 64-byte section trace (J0) sequence and the 16- or 64byte path trace (J1) sequence into internal register banks. · Extracts the DCC channels (D1-D3 and D4-D12) for optional external processing. · Detects Loss Of Signal (LOS), Out Of Frame (OOF), Loss Of Frame (LOF), line Alarm Indication Signal (AIS), line Remote Defect Indication (RDI-L), Loss Of Pointer (LOP), path AIS, path RDI (RDI-P) and Loss Of Cell Delineation (LCD). · Counts received section B1 errors, line B2 errors, line FEBEs, path B3 errors and path FEBEs for performance monitoring purposes.
APPLICATIONS
· · · · · ATM Switching Systems ATM Access Systems LAN Switches, Hubs and Routers ATM Test Equipment SONET or SDH ATM Interfaces
RECEIVE SECTION
· Filters and captures the automatic protection switch channel (K1, K2) bytes in readable registers and detects APS byte failure.
