Overview
The 82V2082PFG8 is a dual-channel Line Interface Unit (LIU) from the Renesas 82V2082 series, designed for E1/T1/J1 long-haul and short-haul telecommunications applications. It operates on a single 3.3 V power supply with a voltage range of 3.13 V to 3.47 V. The component is housed in a TQFP-128 surface-mount package and supports serial interface communication. It functions as a telecom interface IC providing line interface capabilities for digital transmission systems.
Feature Summary
- Dual-channel architecture supporting simultaneous E1/T1/J1 line interfacing
- Integrated LIU functionality for long-haul and short-haul transmission environments
- Single 3.3 V power supply operation for simplified system design
Applications
- E1/T1/J1 long-haul line interface units
- E1/T1/J1 short-haul line interface units
- Telecommunications network equipment requiring dual-channel LIU integration
Procurement Notes
Verify the specific suffix 'G8' against official Renesas documentation to confirm reel packaging and RoHS compliance status. Confirm current production status as distribution sources may list varying availability or obsolescence notices. Ensure the ordering quantity aligns with the factory reel pack size of 750 units if applicable.
Selection Notes
Select this component when a dual-channel LIU solution is required for E1/T1/J1 standards. Compare against the 82V2082PF variant for package differences, noting that the PF version uses an 80-TQFP package while the PFG8 utilizes a TQFP-128. Verify thermal requirements and humidity sensitivity handling procedures during assembly.
Part Context
This part belongs to the 82V2082 family of telecom interface ICs manufactured by Renesas Electronics. It serves as a successor or alternative to older variants like the 82V2082PF, which has been discontinued. The device integrates line interface unit functions specifically optimized for digital carrier transmission systems.
Replacement Considerations
The 82V2082PFG is listed as a direct substitute for the discontinued 82V2082PF. Verify pinout compatibility between the 128-pin PFG8 and the 80-pin PF variant before substitution, as package differences may require PCB redesign.
