82V2042EPFG8

Overview

The 82V2042EPFG8 is a dual-channel Line Interface Unit (LIU) manufactured by Renesas Electronics, designed for telecommunications applications. It operates within a supply voltage range of 3.13 V to 3.47 V and supports both short-haul and long-haul transmission modes. The device integrates two independent channels for E1/T1/J1 interface connectivity. It is housed in a 128-pin TQFP package with dimensions of 14x20 mm. The component functions as a transceiver, facilitating signal transmission and reception over telecom lines.

Feature Summary

• Dual-channel architecture supporting simultaneous E1, T1, or J1 line interfacing
• Integrated transceiver functionality for line interface unit applications
• Supports both short-haul and long-haul transmission configurations

Applications

• Telecommunications network infrastructure equipment
• E1/T1/J1 line interface units
• Digital carrier systems requiring dual-channel LIU capabilities

Procurement Notes

Verify the specific suffix 'PFG8' against official Renesas documentation to confirm package type and moisture sensitivity level. Ensure compatibility with RoHS3 standards if required by regional regulations. Confirm availability status directly with authorized distributors as lead times may vary. Validate that the 128-TQFP package matches the target PCB footprint requirements before procurement.

Selection Notes

Select this component when a dual-channel LIU solution is required for E1, T1, or J1 interfaces. Compare power consumption specifications against system constraints, noting the typical supply current. Ensure the operating temperature range meets the environmental conditions of the deployment site. Verify that the 3.3V logic levels are compatible with the host processor or controller interface.

Part Context

This part belongs to the 82V2044 series family of telecom interface ICs from Renesas. It shares functional similarities with other members like the 82V2044EPFG but offers specific channel configurations. The series is designed for robust performance in digital telecommunication environments, providing reliable line interfacing for standard PDH networks.

Replacement Considerations

Check for direct pin-to-pin replacements within the 82V2044 series. Verify if the 82V2044EPFG serves as a compatible alternative based on official substitution lists. Ensure any substitute maintains the same 128-TQFP package and electrical characteristics.
