PM5348-RI General Description

FEATURES Provides two independent SATURN®-compatible ATM PHY channels in one chip. Provides hardware and software backward compatibility with the industry-standard PM5346 S/UNI®-155-LITE chip. Implements the ATM Transmission Convergence (TC) sublayer according to ATM Forum specifications using the SONET/SDH 155.52 Mbit/s STS-3c/ STM-1 and SONET 51.84 Mbit/s STS-1 formats. NRZ data format supports category-5 Unshielded Twisted Pair (UTP-5) or Shielded Twisted Pair (STP) wiring and optical datalink modules for fiber optic cable. Includes on-chip clock recovery and clock synthesis, compliant to Bellcore and ITU-T requirements. Operates in timing master or timing slave (loop timed LAN) modes. Frames to SONET framing bytes (A1, A2), processes the section and line Bit Interleaved Parity (B1, B2) and the Far-End Block Error (Z2) bytes. Interprets the H1, H2, and H3 payload pointer bytes. Processes the SONET path overhead BIP-8 (B3), signal label (C2) and path status (G1) bytes. Allows for protection switching by monitoring the APS (K1, K2) bytes, bit error rate thresholds and far-end synchronization status (S1) bits and providing interrupts when error conditions are detected.* Inserts and extracts ATM payloads using ATM cell delineation. Provides on-chip 4-cell FIFO buffers in both transmit and receive paths. Operates with a backward compatible dual 8-bit plus parity or a multi-PHY compatible 16-bit plus parity* SATURN-Compliant Interface for PHYsical layer devices (SCI-PHY). Cell interface is also compatible with ATM Forum Level 2 UTOPIA directmode specifications. Provides a generic 8-bit microprocessor bus interface for configuration, control, and monitoring. Provides TTL/CMOS compatible inputs and outputs and differential PECL inputs. Low power, +5 V CMOS technology. Packaged in a 28 mm by 28 mm 160-pin Plastic Quad Flat Pack (PQFP).APPLICATIONS ATM Switches and Hubs ATM Routers Multichannel ATM Servers
