82V2081PP8

Overview

The IDT82V2081 is a single-channel T1/E1/J1 Line Interface Unit (LIU) designed for long haul and short haul applications. It operates on a single 3.3 V power supply with 5 V tolerant digital interfaces. The device integrates an adaptive equalizer, clock/data recovery, AMI/B8ZS/HDB3 encoding/decoding, and jitter attenuation. It supports selectable line terminating impedances of 75 Ω, 100 Ω, 110 Ω, and 120 Ω. Receiver sensitivity exceeds -36 dB at 772 KHz and -43 dB at 1024 KHz. The component is available in 44-pin TQFP and 48-pin QFN packages.

Feature Summary

Supports HPS (hitless protection switching) for 1+1 protection without external relays
Programmable switchability between T1, E1, and J1 standards allowing one bill of material for various line conditions
Integrated PRBS/QRSS generation and detection circuits to facilitate network maintenance
Provides driver short-circuit protection and internal protection diodes for line drivers

Applications

LAN and WAN equipment
Wireless base stations
CSU/DSU equipment
Frame relay access devices

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and environmental compliance. Confirm current production status as legacy components may be subject to discontinuation notices. Ensure compatibility with existing system interfaces before procurement.

Selection Notes

Select this component when a single-channel LIU supporting T1, E1, or J1 protocols is required. Verify that the application environment accommodates the specified operating temperature range. Confirm interface requirements match the supported serial, multiplexed, or hardware control modes.

Part Context

The IDT82V2081 belongs to the 82V2081 series of telecom interface ICs manufactured by Renesas Electronics Corporation. It serves as a specialized line interface unit for telecommunications infrastructure, providing physical layer connectivity for standard digital carrier signals.
