XRT83VSH38IB

Overview

The XRT83VSH38IB is an eight-channel short-haul T1/E1 Line Interface Unit (LIU) manufactured by MaxLinear. It integrates line interface capabilities for telecommunications applications, supporting both T1 and E1 standards over short-distance copper pairs. The device operates within a specific industrial temperature range and utilizes a BGA-225 package for surface mount installation. This component is designed to provide robust signal conditioning and line driving for digital subscriber lines in access networks.

Feature Summary

• Integrates eight independent channels for simultaneous T1 and E1 line interfacing
• Optimized for short-haul transmission distances on twisted-pair copper media
• Supports standard digital telephony framing requirements without external processors

Applications

• Digital Subscriber Line Access Multiplexer (DSLAM) equipment
• Network termination units for short-range telecom links
• Industrial control systems requiring isolated T1/E1 connectivity

Procurement Notes

Verify the exact suffix designation, as the provided model lacks the final character found in public listings like XRT83VSH38IB-F. Confirm end-of-life status with the manufacturer, as similar variants are marked discontinued. Request the official datasheet to validate pin compatibility and electrical specifications before integration into new designs.

Selection Notes

Select this component when eight-channel short-haul T1/E1 LIU functionality is required in a compact form factor. Ensure the application distance aligns with short-haul specifications rather than long-haul requirements. Compare against the XRT83SL38IB if clock synthesis or jitter cleaning features are needed instead of direct line interfacing.

Part Context

This part belongs to the XRT83 series of telecom interface ICs from MaxLinear. It complements other channel counts such as four-channel or fourteen-channel variants. The series supports various packaging options including BGA and TQFP to suit different board space constraints in telecommunications infrastructure.

Replacement Considerations

Public records indicate that the XRT83VSH38IB-F variant is discontinued. Engineers should evaluate the XRT83VL38ES or XRT86VX38IB256-F as potential functional alternatives, though pinouts and feature sets must be verified against the original design requirements.
