82V2058DAG

Overview

The 82V2058DAG is an eight-channel E1 short haul Line Interface Unit (LIU) manufactured by Renesas Electronics. It integrates adaptive equalization, clock and data recovery, line decoding/encoding, and a jitter attenuator within a single device. The component operates on a 3.3 V supply voltage with a maximum rating of 3.47 V and a minimum of 3.13 V. It functions within a temperature range of -40°C to +85°C. The unit is housed in a TQFP-144 package with a pitch of 0.5 mm and dimensions of 20.0 x 20.0 x 1.4 mm. It supports parallel and serial interfaces for telecom applications.

Feature Summary

• Integrates adaptive equalizer for signal conditioning
• Performs clock and data recovery operations
• Includes built-in jitter attenuator functionality

Applications

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

Procurement Notes

This component is officially classified as End-of-Life (EOL) by the manufacturer. Availability is restricted, and it may not be sold in all regions through standard distributors. Verification of current stock status and alternative sourcing channels is required before procurement planning. Compliance documentation such as RoHS details should be reviewed against specific project requirements.

Selection Notes

Designers must account for the moisture sensitivity level (MSL 3) when handling this surface-mount device. The TQFP-144 package requires appropriate PCB layout considerations for thermal management and signal integrity. Since the part is obsolete, replacement strategies should prioritize compatible octal LIUs from the same family or newer generations that maintain pin compatibility and functional equivalence.

Part Context

The 82V2058DAG belongs to the 82V2058 series of telecom interface ICs. It serves as the TQFP-144 variant of the 82V2058BBG, which utilizes a PBGA-160 package. Both variants provide identical eight-channel E1 short haul LIU capabilities. The D suffix denotes the plastic quad flat package format, distinguishing it from the ball grid array option while maintaining the same electrical specifications.

Replacement Considerations

The 82V2058BBG is a direct package alternative within the same series. For design updates, engineers may consider other octal LIUs from the 82V2048 series if form factor changes are acceptable.
