82P2281PF8

Overview

The 82P2281PF8 is a single-channel T1/E1/J1 transceiver manufactured by Renesas Electronics. It integrates a Line Interface Unit (LIU) and framer, supporting data rates up to 2.048 Mb/s. The device operates on dual power supplies: 1.68 V to 1.98 V for digital logic and 3 V to 3.6 V for analog circuits. It features programmable short/long haul line drive levels and supports clock recovery with Synchronization Status Message (SSM) handling. The component is housed in an 80-pin TQFP package (14x14 mm) and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates Line Interface Unit and framer for T1, E1, and J1 protocols
• Supports programmable short and long haul line drive configurations
• Includes hardware clock recovery and Synchronization Status Message processing

Applications

• Central Office telecommunications equipment
• Private Automatic Branch Exchange (PABX) systems
• Wireless base station interfaces
• T1/E1/J1 ATM gateways and multiplexers

Procurement Notes

This component is identified as obsolete and no longer manufactured by Renesas Electronics. Verification of availability requires checking authorized distributors for remaining stock or approved replacement part numbers. Ensure any substitute components maintain pin compatibility and electrical specifications before integration into existing designs.

Selection Notes

Select this component only if legacy support for the 82P2281 family is required. Verify that the 80-pin TQFP footprint matches the PCB layout. Confirm that the dual voltage supply requirements (1.8V and 3.3V) are compatible with the system power architecture. Check for RoHS compliance status as older revisions may not meet current environmental standards.

Part Context

The 82P2281PF8 belongs to the IDT/Renesas 82P228x series of telecom interface ICs. This family provides integrated solutions for synchronous serial transmission. The 'PF8' suffix typically denotes the specific package type and lead-free status variant within the 80-TQFP form factor. It serves as a direct predecessor to newer generations of integrated transceivers.

Replacement Considerations

The 82P2281PFG is listed as a direct replacement for the 82P2281PF. Both parts share the same functional specification and 80-TQFP packaging. Verify that the 'G' suffix indicates the correct lead-free material composition required for the target assembly process.
