XR17V354IB176-F

Overview

The XR17V354IB176-F is an octal PCIe UART interface integrated circuit manufactured by MaxLinear. It provides four independent UART channels within a single package, bridging PCI Express bus signaling to serial communication protocols. The device features a 256-byte FIFO storage capacity per channel and supports data rates up to 31.25 Mb/s. It operates on a 3.3 V power supply with a voltage range of 2.97 V to 3.63 V and draws approximately 100 mA of operating current. The component is housed in a 176-pin FPBGA package and functions reliably within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrates four high-speed UART channels into a compact PCIe bridge solution
• Provides substantial 256-byte FIFO buffering for each individual channel
• Supports extended industrial temperature operation for robust environmental performance

Applications

• Industrial automation systems requiring multiple serial connections
• Telecommunications infrastructure equipment
• Embedded computing platforms needing PCIe expansion for serial I/O

Procurement Notes

Verify the specific suffix designation against official MaxLinear documentation to confirm exact electrical characteristics and packaging options. Ensure compatibility with the target system's PCIe lane availability and power delivery constraints before finalizing procurement orders.

Selection Notes

Select this component when four independent serial ports are required within a PCIe-based architecture. Compare against other members of the XR17V35x family if different channel counts or package sizes better suit the board layout constraints.
