82V2048BBG8

Overview

The 82V2048BBG8 is an octal T1/E1/J1 short haul line interface unit (LIU) manufactured by Renesas Electronics. It operates on a single 3.3 V power supply with a voltage range of 3.13 V to 3.47 V. The device integrates eight independent LIU channels within a 160-pin PBGA package. Key internal functions include adaptive equalization, clock and data recovery, line decoding/encoding, and jitter attenuation. It supports serial control interfaces for configuration and status monitoring.

Feature Summary

• Integrates eight independent line interface units for simultaneous T1, E1, or J1 signal processing.
• Includes built-in adaptive equalizers and clock/data recovery circuits for signal integrity.
• Supports serial control interface for device configuration and status register access.

Applications

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

Procurement Notes

This component is designated as obsolete and has reached end-of-life status. Availability is restricted, and sourcing new units may be difficult. Engineers should verify the authenticity of any remaining stock through authorized channels. Replacement planning is recommended due to discontinuation notifications from the manufacturer.

Selection Notes

Select this part for designs requiring high-density T1/E1/J1 short-haul connectivity in a compact surface-mount package. Verify that the system architecture supports the required 3.3 V logic levels and serial control protocols. Ensure the PCB layout accommodates the thermal and pin density requirements of the 160-pin PBGA form factor.

Part Context

The 82V2048BBG8 belongs to the 82V2048 family of telecom interface ICs. It serves as a successor or variant to earlier versions like the 82V2048BBG, offering similar functionality in a specific packaging configuration. This series is designed for telecommunications applications requiring multiple line interfaces in a single chip solution.

Replacement Considerations

The 82V2058BBG is listed as an alternate product for the 82V2048 series. Verify pin compatibility and feature parity before substitution. Other family members may require schematic and firmware modifications.
