Procurement Notes

This component is officially designated as End-of-Life (EOL) by the manufacturer. Distribution is currently restricted, indicating limited availability through authorized channels. Buyers must verify current stock status directly with suppliers before ordering. Alternative sourcing strategies should be considered due to the discontinuation status.

Selection Notes

Designers requiring this specific eight-channel architecture must account for the EOL status when planning long-term production. Verify that the 1.544/2.048 Mbps rate requirements align with the system design. Since the part is discontinued, ensure that any replacement components maintain compatible pinouts and electrical specifications to avoid extensive redesign efforts.

Part Context

The XRT86VX38IB256-F belongs to the MaxLinear XRT86VX38 series, which focuses on high-performance telecom interface solutions. This series provides integrated framing and LIU capabilities for various network standards. The specific model serves as a core component for managing multiple T1/E1 lines within a single package, simplifying board layout and reducing component count in telecom hardware.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the End-of-Life status, direct replacements may require functional equivalence analysis rather than simple cross-referencing.
