82P2281PF

Overview

The Renesas 82P2281PF is a discontinued single-channel T1/E1/J1 transceiver integrating a Line Interface Unit (LIU) and framer. It operates within a supply voltage range of 3V to 3.6V and draws a maximum supply current of 1.15A. The device supports data rates up to 2.048 Mb/s and features an SPI interface for control. It is housed in an 80-LQFP package with dimensions of 14x14 mm, suitable for surface-mount installation. The component functions across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates line interface unit and framer functionality for single-channel telecommunication applications
• Supports clock recovery and Synchronization Status Message (SSM) insertion and extraction
• Configurable for short-haul and long-haul transmission modes with programmable loss-of-signal levels

Applications

• Central Office equipment
• Private Automatic Branch Exchange (PABX) systems
• Wireless base stations
• T1/E1/J1 ATM gateways and multiplexers
• SONET/SDH add/drop multiplexer equipment

Procurement Notes

This specific part number is officially obsolete and no longer manufactured by Renesas Electronics Corporation. Verification of availability should focus on the active replacement model, 82P2281PFG. Procurement requires confirmation that the substitute component meets all original electrical and mechanical specifications. Users must review Product Change Notices regarding lead-free status and packaging updates before acquisition.

Selection Notes

Designers requiring this component should select the direct replacement 82P2281PFG, which maintains functional compatibility. Ensure the new procurement includes verification of the RoHS compliance status, as the original PF suffix may indicate non-compliant materials. Confirm that the 80-TQFP package dimensions match the existing printed circuit board footprint without modification.

Part Context

The 82P2281 belongs to the IDT/Renesas 82P228x family of high-performance telecom transceivers. This series is designed for digital cross-connect systems and network interfaces. The PF suffix denotes the specific 80-lead Thin Quad Flat Package variant. The product transitioned from Integrated Device Technology (IDT) to Renesas following corporate acquisitions.

Replacement Considerations

The confirmed direct replacement is the 82P2281PFG. This variant offers identical pinout and functional performance. Verify that the PFG suffix indicates lead-free composition and updated manufacturing processes compared to the obsolete PF version.
