PMC-Sierra,Inc. PM7339 S/UNI(R)-CDB Quad Cell Delineation Block Device FEATURES * Quad cell delineation block operating up to a maximum rate of 52 Mbit/s. * Provides a UTOPIA Level 2compatible ATM-PHY Interface. * Implements the Physical Layer Convergence Protocol (PLCP) for DS1 transmission systems according to the ATM Forum User Network Interface specification and ANSI TA-TSY000773, TA-TSY-000772, and E1 transmission systems according to the ETSI 300-269 and ETSI 300-270. * Supports SMDS PLCP and ATM Direct Mapping into various rate transmission systems in the following formats: * E1 (2.048 Mbit/s) in CRC-4 and PCM30; * T1 (1.544 Mbit/s) in ESF and SF; * Arbitrary Cell Rate (up to 52 Mbit/s) with ATM Direct Mapping only. * Uses the PMC-Sierra PM4341 T1XC, PM4344 TQUAD, PM6341 E1XC, and PM6344 EQUAD T1 and E1 framer/line interface chips for DS-1 and E1 applications. * Provides programmable pseudorandom test pattern generation, detection and analysis features. * Provides performance monitoring counters suitable for accumulation periods of up to 1 second. (for use with PPP packets), and accumulates the number of received idle cells, the number of received cells written to the FIFO and the number of HCS errors. * Provides a four cell FIFO for rate decoupling between the line, and a higher layer processing entity. FIFO latency may be reduced by changing the number of operational cell FIFOs. * Provides programmable pseudorandom test-sequence detection and analysis features. RECEIVER SECTION * Provides PLCP frame synchronization, path overhead extraction and cell extraction for DS1 and E1 PLCP formatted streams. * Provides a 50 MHz 8-bit wide or 16-bit wide UTOPIA FIFO buffer in the receive path with parity support, and multi-PHY (Level 2) control signals. * Provides ATM framing using cell delineation. ATM cell delineation may optionally be disabled to allow all cell bytes to pass regardless of cell delineation status. * Provides cell descrambling, header check sequence (HCS) error detection, idle cell filtering, header descrambling TRANSMITTER SECTION * Provides a 50 MHz 8-bit wide or 16-bit wide Utopia FIFO buffer in the transmit path with parity support and multi-PHY (Level 2) control signals. * Provides optional ATM cell scrambling, header scrambling (for use with PPP packets), HCS generation/insertion, programmable idle cell insertion, diagnostics features and accumulates transmitted cells read from the FIFO.

FIFO latency may be reduced by changing the number of operational cell FIFOs. * Provides an 8 kHz reference input for locking the transmit PLCP frame rate to an externally applied frame reference. * Provides programmable pseudorandom test sequence generation (up to 232-1 bit length sequences conforming to ITU-T O.151 standards). Diagnostic abilities include single bit error insertion or error insertion at bit error rates ranging from 10-1 to 10-7. LOOPBACK FEATURES * Provides for diagnostic loopbacks and line loopbacks. APPLICATIONS * ATM Switches, Multiplexers, and Routers. * SMDS Switches, Multiplexers and Routers. * DSLAM. * Integrated Access Devices (IAD). GENERAL * Provides an 8-bit microprocessor interface for configuration, control and status monitoring. * Provides a standard five signal P1149.1 JTAG test port for boundary scan board test purposes. * Low power 3.3 V CMOS technology with 5 V tolerant inputs. * Available in a high density 256-pin SBGA package (27 mm x 27 mm).
