Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging versus 'T' or standard tray options when sourcing replacements. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the lead-free designation matches project requirements. Cross-reference the exact part number against current distributor inventories as availability may vary by region.

Selection Notes

Select this component when designing systems requiring eight simultaneous serial ports without increasing board space significantly. Consider the 144-LQFP footprint for PCB layout constraints. Evaluate the 6.25 Mb/s speed limit against application bandwidth needs. Verify compatibility with existing PCI bus architectures and ensure power supply stability within the 4.5V to 5.5V range for optimal performance.

Part Context

This part belongs to the XR17D158 series of universal PCI bus UARTs from MaxLinear. It serves as a bridge between parallel PCI buses and serial asynchronous communications. The series is known for integrating multiple UARTs into single chips to reduce system complexity. It complements other interface solutions like the XR33052 transceivers for physical layer connectivity.

Replacement Considerations

XR17C158IV-F is a recommended manufacturer substitute. XR17V358IB176-F offers PCIe compatibility with larger FIFOs but requires different pinout adaptation.
