82V2052EPF8

Overview

The Renesas Electronics Corporation 82V2052EPF8 is a dual-channel E1 short haul Line Interface Unit (LIU) designed for telecom interface applications. It operates on a 3.3 V supply voltage with a range of 3.13 V to 3.47 V. The device integrates an adaptive equalizer, clock data recovery, line decoding/encoding, and one jitter attenuator. It is housed in an 80-TQFP package measuring 14x14 mm with a 0.65 mm pitch. The component supports surface mount installation and functions within a temperature range of -40°C to 85°C.

Feature Summary

• Integrates adaptive equalizer for signal conditioning
• Performs clock data recovery and line encoding/decoding
• Includes one jitter attenuator for signal integrity

Applications

• Local Area Network (LAN) equipment
• Wide Area Network (WAN) infrastructure
• Routers and gateways
• Wireless base stations

Procurement Notes

Verify current availability status as distribution channels may report limited stock or discontinuation. Confirm RoHS compliance details and moisture sensitivity level prior to ordering. Ensure the specific suffix matches the required package type and manufacturing origin. Check for any product change notices affecting assembly sites or labeling.

Selection Notes

Select this component for E1 short haul applications requiring integrated signal processing. Compare against long haul variants if extended distance support is needed. Verify pin compatibility with existing PCB layouts due to the 80-TQFP form factor. Consider thermal management requirements for the specified operating temperature range.

Part Context

This part belongs to the 82V2052 series of Line Interface Units. It shares functional similarities with other IDT/Renesas LIU devices but is distinct in its dual-channel E1 short haul configuration. The 82V2052EPF8 specifically denotes the TQFP package variant, differentiating it from other package options like the EPFG.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify cross-reference compatibility with IDT82V2052EPF8 alias if sourcing from legacy inventories.
