Device Overview

Summary

The PM5319 ARROW-622 is a part of Microchip's portfolio of SONET/SDH Metro transport framers and mappers, supporting interface rates between OC-3/STM-1 (155.52 Mbit/s) and OC-12/STM-4 (622.08 Mbit/s). In addition, it integrates a flexible three-port DS3/E3/EC-1 interface supporting mapping/demapping of DS3/E3 into/from STS-1, AU-3 or TU-3.

Applications
• SONET/SDH Add/Drop Multiplexers
• Terminal Multiplexers
• Customer Premise Equipment
• Media Gateways
• Multiservice Provisioning Platforms
• Channelized Router Interfaces
• Digital Cross-Connects

Additional Features
  • Interface rate software selectable between OC-3/STM-1 (155.52 Mbit/s) and OC-12/STM-4 (622.08 Mbit/s) rates
  • Integrated clock recovery & synthesis allows direct interface to low-cost optical transceivers
  • Integrated clock synthesis generates line clock from 77.76 MHz reference
  • Complies with Bellcore, ANSI, and ITU specifications for Jitter Tolerance and Jitter Generation
  • High order path processing and alignment to STS-1/AU-3/TU-3 level
  • Full access to all SONET/SDH Transport overhead bytes via a dedicated serial port
  • Full access to all SONET/SDH STS-1/AU-3/TU-3 path overhead bytes via a dedicated serial port
  • Full access to all DCC bytes via a dedicated serial interface
  • Ring Control port provides real time detection of error conditions and insertion of alarms such as AIS & RDI
  • Section and Path Trace filter and monitor checks for Trace Identifier Mismatch (TIM) and Trace Identifier Unstable (TIU) conditions
  • Flexible three-port DS3/E3/EC-1 Interface
  • Supports clear channel mapping/demapping of DS3 or E3 into/from STS-1, AU-3, or TU-3
  • Fully digital desynchronizers require no external PLLs for standardscompliant operation
  • Integrated desynchronization CSU allows low rate reference clock at 44.736 MHz, 34.368 MHz, or 51.84 MHz
  • Bi-directional digital jitter attenuation for DS3 and E3 streams allows interfacing to low cost LIUs
  • Full bi-directional performance monitoring for DS3, E3, and EC-1 streams
  • Full access to DS3/E3/EC-1 Overhead bytes
  • Provides an industry standard 8-bit, 77.76 MHz telecombus interface
  • Multi-drop capability allows multiple devices to share the add/drop bus for redundancy or multiplexing purposes
  • Full Time Slot Interchange (TSI) allows flexible mixing of traffic from the SONET/SDH and DS3/E3/EC-1 Interfaces
  • Supports diagnostic 223-1 pseudorandom bit-sequence (PRBS) generation and monitoring
  • Provides a standard JTAG test-port for boundary scan board-test purposes
  • Provides a generic 16-bit microprocessor interface for control and monitoring
  • 15x15mm 196 ball CABGA package allows for flexible placement and routing
