Product Overview
  • Single chip 16-channel ATM and POS User Network Interface operating at 155 Mbit/s.
  • Implements the ATM Forum User Network Interface Specification and the ATM physical layer for Broadband ISDN according to CCITT Recommendation I.432.
  • Implements the Point-to-Point Protocol (PPP) over SONET/SDH specification according to RFC 2615(1619)/1662 of the PPP Working Group of the Internet Engineering Task Force (IETF).
  • Processes sixteen bit-serial 155 Mbit/s STS-3c (STM-1) data streams with on-chip clock and data recovery and clock synthesis.
  • Complies with Bellcore GR-253-CORE jitter tolerance, jitter transfer and intrinsic jitter criteria.
  • Each channel provides termination for SONET Section, Line and Path overhead or SDH Regenerator Section, Multiplexer Section and High Order Path overhead.
  • Provides UTOPIA Level 3 32-bit wide System Interface (clocked up to 104 MHz) with parity support for ATM applications.
  • Provides SATURN POS-PHY Level 3 32-bit System Interface (clocked up to 104 MHz) for Packet over SONET (POS), or ATM applications.
  • Supports line loopback from the line side receive stream to the transmit stream and diagnostic loopback from the line side transmit stream to the line side receive stream interface.
  • Provides support for automatic protection switching including a bi-directional 4-bit PECL 622 MHz port for external APS with mate device.
  • Built-in APS cross-connect for internal and external 1+1 and 1:n protection switching.
  • Provides a standard five signal IEEE 1149.1 JTAG test port for boundary scan board test purposes.
  • Provides a generic 16-bit microprocessor bus interface for configuration, control, and status monitoring.
  • Low power 2.5 V CMOS core logic with 3.3 V CMOS/TTL compatible digital inputs and digital outputs. PECL inputs and outputs are 3.3 V compatible.
  • Industrial temperature range (-40 °C to +85 °C).
  • 520 pin SBGA package.
  • Pin and software compatible with the PM5358 S/UNI 4x622.

Typical Applications include:

  • ATM and Multiservice Switches, Routers, and Switch/Routers.
  • SONET/SDH Add/Drop Multiplexers with data processing capabilities
  • Uplink Cards.
  • SONET/SDH ATM/POS Test Equipment.
  • SONET/SDH Transport Equipment.
