82P2282PFG

Overview

The 82P2282PFG is a dual-channel T1/E1/J1 transceiver manufactured by Renesas Electronics. It integrates line interface unit and framer functions for telecommunications applications. The device operates on a single 3V to 3.6V supply voltage with a maximum operating current of 20 mA. It supports data rates up to 2.048 Mb/s and features parallel, serial, JTAG, and SPI interfaces. The component is housed in a 100-TQFP (14x20 mm) surface-mount package. It functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrates dual T1/E1/J1 transceivers with line interface and framing capabilities
• Supports multiple communication protocols including SPI, JTAG, and parallel interfaces
• Includes clock recovery and synchronization status message handling

Applications

• Central Office equipment
• Wireless Base Stations
• T1/E1/J1 ATM Gateways
• Multiplexers and LAN/WAN Routers

Procurement Notes

Verify the specific suffix PFG against official Renesas documentation to confirm the 100-TQFP package variant. Confirm RoHS compliance status as some related variants may differ. Check for obsolescence notices or product change notifications prior to procurement. Ensure availability aligns with project timelines due to potential lifecycle constraints.

Selection Notes

Select this component for designs requiring dual-channel T1/E1/J1 connectivity with integrated framing. Verify that the 100-pin TQFP footprint matches the PCB layout. Ensure the system power supply remains within the 3V to 3.6V range. Confirm interface compatibility with the host controller's SPI or parallel bus requirements.

Part Context

This part belongs to the 82P228x series of telecom interface ICs. It serves as a successor or variant to earlier IDT-branded versions. The device is designed for high-reliability telecommunication infrastructure. It replaces older discrete solutions by integrating transceiver and framer functions into a single chip.

Replacement Considerations

The 82P2282PF8 is a direct substitute with identical functionality but differs in packaging configuration. Verify pinout compatibility when switching between tray and reel/cut tape formats. Ensure thermal management remains adequate for the alternative package type.
