82V2108PXG

Overview

The Renesas 82V2108PXG is an octal T1/E1/J1 framer integrated circuit designed for telecommunications applications. It features a parallel multiplexed or non-multiplexed microprocessor interface for configuration. The device operates within a supply voltage range of 2.97V to 3.63V and draws a maximum supply current of 160mA. It supports operation across an industrial temperature range of -40°C to +85°C. The component is housed in a 128-BFQFP package with dimensions of 14x20mm, providing eight independent framing channels.

Feature Summary

• Supports global configuration as an octal E1 or T1/J1 framer with independent channel mode selection
• Configurable via parallel multiplexed or non-multiplexed microprocessor interface
• Designed for high-reliability telecommunications infrastructure environments

Applications

• T1/E1/J1 line interface units (LIUs)
• Digital cross-connect systems (DCS)
• Time-division multiplexing (TDM) equipment

Procurement Notes

Verify the specific suffix 'G' against official Renesas documentation to confirm RoHS compliance status, as standard 'PX' variants may differ. Confirm end-of-life status through manufacturer notices, as this family has been subject to discontinuation announcements. Ensure compatibility with existing board layouts for the 128-BFQFP footprint before procurement.

Selection Notes

Select this component when an octal framing solution is required for T1, E1, or J1 standards. Verify that the system design accommodates the 128-pin BFQFP package size. Ensure the host processor can support the required parallel interface protocol for configuration and data transfer.

Part Context

This part belongs to the 82V2108 family of telecom interface ICs. It serves as a frame synchronization and bit-slipping device for digital carrier signals. The product line includes variants with different packaging and compliance suffixes, such as PX and PX8, which share the same core functionality but may differ in environmental specifications.

Replacement Considerations

Check for IDT82V2108PXG as an alias. Evaluate IDT82V2108PX8 for tape-and-reel packaging alternatives if available. Consult Renesas for current active replacements due to potential end-of-life status.
