PM5316-BGI

Telecom Overview

The PM5316-BGI is a monolithic quad-channel SONET/SDH Payload Extractor and Aligner manufactured by Microchip Technology. It operates at serial interface speeds of 155.52 Mbit/s, supporting STS-3 (STM-1/AU-3) or STS-3c (STM-1/AU-4) interface applications. The device integrates clock recovery and synthesis for direct optical module interfacing. Each channel terminates transport overheads for three STS-1 paths or one STS-3c path, mapping payloads to system timing references via pointer processing. It supports Automatic Protection Switching (APS) and Time Slot Interchange (TSI) functions for grooming twelve STS-1 paths.

Telecom Feature Summary

• Monolithic four-channel architecture for SONET/SDH payload extraction and alignment
• Integrated clock recovery and synthesis capabilities
• Support for Automatic Protection Switching (APS) with K1/K2 byte filtering
• Time Slot Interchange (TSI) functionality for traffic grooming

Telecom Applications

• STS-3 (STM-1/AU-3) interface applications
• STS-3c (STM-1/AU-4) interface applications
• Direct interface to optical modules
• TelecomBus ADD and DROP interfaces for path grooming

Telecom Procurement Notes

Verify the specific suffix BGI against official Microchip documentation to confirm package type, temperature grade, and tape-and-reel specifications. Ensure compatibility with required operating voltage levels and interface standards before procurement. Cross-reference the active status and lead times through authorized distribution channels.

Telecom Selection Notes

Select this component for systems requiring quad-channel SONET/SDH framer and aligner functionality at 155.52 Mbit/s. Consider the integrated clock recovery features if direct optical module interfacing is needed. Evaluate the TSI capacity for grooming twelve STS-1 paths against system bandwidth requirements.

Telecom Part Context

This part belongs to the PM5316 family of SONET/SDH payload extractors and aligners. These devices are designed for high-performance telecommunications infrastructure, providing essential framing, alignment, and overhead processing capabilities for synchronous digital hierarchy networks.

Telecom Replacement Considerations

Check for updated revisions within the PM5316 series. Verify pin-to-pin compatibility and electrical characteristics if considering alternative vendors offering similar quad-channel SONET/SDH aligners.
