PM5366-PGI

Overview

The PM5366-PGI is a specialized integrated circuit from Microchip Technology designed for telecommunications applications. It functions as an 84/63 channel T1/E1 interface device, incorporating VT1.5 and VT2 mapping capabilities alongside M13 multiplexing. The component supports multiple digital interfaces including Bus, JTAG, and Microprocessor connections. It operates with dual supply voltage ranges of 1.65V to 1.95V and 3.04V to 3.56V. The device is housed in a 324-pin Ball Grid Array (BGA) package, specifically identified as 324-BBGA or 324-PBGA with dimensions of 23x23 mm.

Feature Summary

• Integrates T1/E1 channel processing with VT1.5 and VT2 mapping functionality
• Supports M13 multiplexing for efficient data transmission
• Provides flexible connectivity through Bus, JTAG, and Microprocessor interfaces
• Features high configurability to adapt to specific system requirements

Applications

• T1/E1 telecommunications network infrastructure
• Voice over IP (VoIP) gateway implementations
• Digital signal processing systems requiring channel mapping
• Multiplexer devices in carrier-grade communication equipment

Procurement Notes

Verify component authenticity through authorized Microchip distributors due to obsolete status. Confirm package integrity and pin alignment for the 324-BBGA form factor. Ensure compatibility with required supply voltages of 1.65V-1.95V and 3.04V-3.56V. Check for alternative qualified sources if original manufacturing availability is limited.

Selection Notes

Select this component for applications requiring integrated T1/E1 channel management and M13 multiplexing. Consider the dual voltage operation for mixed logic level environments. Evaluate the 324-pin BGA footprint against PCB layout constraints. Verify interface support for Bus, JTAG, and Microprocessor protocols matches system architecture needs.

Part Context

This part belongs to Microchip's specialized interface IC portfolio, targeting telecom and datacom sectors. It consolidates channel mapping and multiplexing functions into a single package. The device replaces discrete solutions by integrating VT1.5/VT2 mapping directly with T1/E1 physical layer processing. It serves as a key component in modernizing legacy telecommunication hardware.

Replacement Considerations

The PM5366-PGI is listed as obsolete. No direct public substitute part numbers are confirmed in available documentation. Engineers should consult Microchip for current equivalent recommendations or design-in alternatives that match the 324-BBGA package and functional specifications.
