82V2058DA

Overview

The 82V2058DA is an octal E1 short haul line interface unit manufactured by Renesas Electronics. It integrates eight independent line interface units within a single package to support high-density telecommunications applications. The device incorporates adaptive equalization, clock and data recovery, line decoding and encoding, and jitter attenuation functions. Designed for operation in the industrial temperature range of -40°C to +85°C, it utilizes a TQFP-144 surface-mount package with a pitch of 0.5mm. The component operates on a nominal 3.3V supply voltage and supports parallel and serial interfaces for system integration.

Feature Summary

• Integrates eight independent E1 short haul line interface channels
• Includes built-in adaptive equalizer for signal integrity
• Performs clock and data recovery operations
• Provides line decoding and encoding capabilities

Applications

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

Procurement Notes

Verify current availability status as this component may be subject to limited distribution or end-of-life restrictions. Confirm moisture sensitivity level handling requirements prior to assembly. Ensure compatibility with existing PCB footprint and thermal management specifications. Review official datasheets for updated pinout definitions and electrical characteristics before finalizing procurement plans.

Selection Notes

Select this component when designing systems requiring multiple E1 short haul connections in a compact form factor. Consider the TQFP-144 package constraints for board layout and soldering processes. Evaluate power consumption profiles against system thermal limits. Verify that the integrated jitter attenuator meets specific network synchronization requirements without external components.

Part Context

This part belongs to the 82V2058 series of telecom interface ICs from Renesas Electronics. It serves as an octal solution for E1 line interfacing, distinct from single-channel variants like the 82V2051E. The DA suffix typically denotes the TQFP-144 package variant. Related parts include the 82V2058BBG which uses a PBGA package.

Replacement Considerations

The 82V2058BBG is listed as an alternate package option within the same functional family. Verify pin-to-pin compatibility and thermal performance differences between the TQFP and PBGA packages before substitution. Consult official discontinuance notices for long-term supply chain implications.
