82V2108PX8

Overview

The Renesas 82V2108PX8 is an octal T1/E1/J1 framer integrated circuit designed for telecommunications applications. It operates within a supply voltage range of 2.97V to 3.63V and draws a maximum supply current of 160mA. The device supports global configuration as either an octal E1 or T1/J1 framer, with independent operation mode control for each of the eight channels. Configuration is managed via a parallel multiplexed or non-multiplexed microprocessor interface. It is housed in a 128-BFQFP package (128-PQFP 14x20) and functions reliably across a temperature range of -40°C to 85°C.

Feature Summary

• Supports flexible global configuration as an octal E1 or T1/J1 framer
• Enables independent channel operation mode configuration after global setting
• Features a parallel multiplexed or non-multiplexed microprocessor interface for control

Applications

• Telecommunications line interface units
• T1/E1/J1 network equipment
• Digital cross-connect systems

Procurement Notes

This component has reached End-of-Life status, with discontinuance notifications issued by the manufacturer. Verification of specific RoHS compliance requires checking the suffix, as the base model may differ from lead-free variants. Sourcing should focus on verified surplus distributors or qualified replacement components due to limited availability.

Selection Notes

Designers must account for the discontinued status when planning long-term production. Verify that the 128-BFQFP footprint matches existing PCB layouts. Ensure the microprocessor interface timing aligns with the parallel multiplexed protocol requirements specified in the datasheet for proper system integration.

Part Context

The 82V2108PX8 belongs to the IDT/Renesas 82V2108 family of telecom interface ICs. This series provides high-density framing solutions for digital transmission standards. The PX8 suffix typically denotes a specific packaging and environmental compliance variant within the broader product line, distinguishing it from tray-packaged versions.

Replacement Considerations

Direct replacements are limited due to the End-of-Life status. Evaluate other octal framers from the same family or newer generations that support T1/E1/J1 standards. Verify pin compatibility and interface protocols before substituting.
