82V2051EPPG

Overview

The Renesas 82V2051EPPG is a single-channel E1 short-haul Line Interface Unit (LIU) designed for telecommunications applications. It integrates an adaptive equalizer, clock and data recovery (CDR), line decoding/encoding, and a jitter attenuator. The device operates on a single 3.3V power supply and supports the E1 line rate standard. It is housed in a 44-pin Thin Quad Flat Package (TQFP) with dimensions of 10mm x 10mm. The component functions as a dedicated interface unit for connecting digital transmission equipment to the network line.

Feature Summary

• Integrates adaptive equalization and clock/data recovery for signal integrity
• Performs line encoding and decoding functions for E1 standards
• Includes built-in jitter attenuation capabilities

Applications

• Local Area Network (LAN) infrastructure
• Wide Area Network (WAN) connectivity
• Wireless base station equipment
• Network gateways and routers

Procurement Notes

Verify availability status carefully as this component may be subject to limited supply or end-of-life conditions. Confirm the specific suffix 'G' corresponds to the RoHS-compliant tape-and-reel packaging variant if required by assembly processes. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity and traceability before procurement.

Selection Notes

Select this component when a single-channel E1 short-haul LIU solution is required with integrated CDR and equalization. Ensure the design accommodates the 44-TQFP package footprint and 3.3V logic levels. Compare against other channel counts in the 82V205x family if multiple ports are needed. Verify that the short-haul specification meets the physical distance requirements of the target application.

Part Context

This part belongs to the Renesas 82V205x series of telecom interface ICs, specifically the Line Interface Units (LIUs). It is functionally related to other variants such as the 82V2051EPP and 82V2051EPPG8, differing primarily in packaging and compliance suffixes. The series is optimized for high-performance digital transmission interfaces in networking hardware.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. The 82V2051EPP and 82V2051EPPG8 are closely related variants within the same product family. Consult official Renesas documentation for any officially recommended replacements due to potential obsolescence.
