XRT83SL34IV-F

Overview

The XRT83SL34IV-F is a telecommunications interface integrated circuit manufactured by MaxLinear. It functions as a four-channel Line Interface Unit (LIU) designed for T1 and E1 applications. The device supports both short-haul and long-haul transmission modes, providing versatile connectivity options for digital telephony networks. It integrates line drivers and receivers to manage signal transmission over twisted-pair copper lines. The component is housed in a surface-mount TQFP-128 package, facilitating integration into compact telecom equipment designs requiring multi-channel interface capabilities.

Feature Summary

• Four independent channel configuration for simultaneous T1/E1 line interfacing
• Support for both short-haul and long-haul transmission operating modes
• Integrated line driver and receiver circuitry for direct connection to copper pairs

Applications

• Digital subscriber line access multiplexers (DSLAMs)
• T1/E1 network termination units
• Telecommunications central office equipment

Procurement Notes

Verify the specific suffix IV-F against current manufacturer documentation to confirm pinout and electrical specifications. Confirm availability status as the product lifecycle may be discontinued or restricted. Ensure compatibility with existing board layouts using the TQFP-128 footprint before procurement.

Selection Notes

Select this component when a four-channel LIU solution is required for mixed T1/E1 environments. Compare channel density and power consumption against single-channel alternatives if space is constrained. Verify that the short-haul/long-haul flexibility meets the specific distance requirements of the target deployment scenario.

Part Context

This part belongs to the XRT83SL34 series of telecom interface ICs from MaxLinear. It shares functional similarities with other members of the family but is distinguished by its four-channel architecture and specific package type. It serves as a core interface component in legacy and modern digital telephony infrastructure.

Replacement Considerations

Check for updated revisions within the XRT83SL34 series. Evaluate cross-compatible parts from the same manufacturer offering identical channel counts and package dimensions. Verify pin-to-pin compatibility before substituting with similar LIU devices.
