Procurement Notes

Verify the exact suffix 'AIB329' against official MaxLinear documentation to confirm pinout and electrical specifications, as suffixes often denote specific package types or temperature ranges. Confirm current availability status directly with authorized distributors, as this component may be subject to discontinuation notices or limited stock conditions. Ensure compliance with relevant RoHS directives before integration into final products.

Selection Notes

Select this component when an octal channel count is required for T1/E1/J1 applications. Compare against the XRT86VL38 series for potential architectural similarities or upgrades. Verify that the operating temperature range and package dimensions meet the target board design constraints. Consult the latest datasheet for detailed timing diagrams and register descriptions to ensure compatibility with the host processor interface.

Part Context

This part belongs to the XRT86 family of telecom interface ICs from MaxLinear, formerly Exar Corporation. The family includes various configurations such as dual, quad, and octal channel options. The XRT86VX38 variant specifically denotes the octal configuration. This lineage provides standardized solutions for digital carrier interfaces in legacy and modern telecom networks.

Replacement Considerations

The XRT86VL38IB329-F is a documented similar part number within the same product family. Verify functional equivalence and pin compatibility before substitution. Check for any updates in the manufacturing process or material composition that might affect mechanical fit or long-term reliability.
