XRT86VL30IV-F

Overview

The XRT86VL30IV-F is a single-channel T1/E1/J1 framer and line interface unit (LIU) manufactured by MaxLinear. It integrates framing, timing, and line driving capabilities for digital telephony applications. The device operates within a supply voltage range of 3.3V and supports an industrial operating temperature range from -40°C to +85°C. It is housed in a surface-mount 128-LQFP package with dimensions of 14x20 mm. The component exhibits moisture sensitivity level 3, allowing for a peak reflow duration of 168 hours. This integrated circuit serves as a complete solution for connecting digital subscriber lines to network infrastructure.

Feature Summary

• Integrates T1, E1, and J1 framing logic with line interface unit functions
• Supports single-channel operation for digital telephony signaling
• Designed for industrial temperature environments

Applications

• T1/E1/J1 digital subscriber line interfaces
• Telecommunications network access equipment
• Digital cross-connect systems

Procurement Notes

This component is officially classified as End-of-Life (EOL). A Product Discontinuance Notification was issued on September 30, 2021. Verification of current availability requires checking authorized distributors for remaining stock or obsolete inventory. Procurement should focus on verifying the authenticity of existing supplies due to the discontinued status.

Selection Notes

Designers requiring this specific single-channel LIU must account for its discontinuation. Selection should prioritize verifying the 128-LQFP footprint compatibility if replacing existing designs. Engineers should evaluate alternative components from the same manufacturer family that offer similar framing and LIU integration but are currently in active production to ensure long-term supply stability.

Part Context

The XRT86VL30IV-F belongs to the XRT86VL30 series of telecom interface ICs. It is part of MaxLinear's portfolio of digital telephony solutions, previously associated with Exar Corporation before acquisition. The device provides a consolidated approach to handling T1/E1/J1 protocols, reducing the need for discrete framing and line driver components in standard telecommunications hardware architectures.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the End-of-Life status announced in September 2021, direct replacements must be identified through official MaxLinear obsolescence management channels or by evaluating newer generations of single-channel LIUs.
