• Compliant with PCI Express Base Specification 1.1
• Integrated Clock and Data Recovery (CDR)
• Supports advanced power management functions
• Includes JTAG boundary scan interface

Applications

• PCI Express link interfaces
• FPGA-based system designs
• High-speed serial data transmission

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and solder process. Ensure compatibility with required voltage levels and temperature ranges before integration. Confirm that the component meets all necessary compliance standards for the intended application environment.

Selection Notes

Select this component for applications requiring a standalone PCIe PHY with low power consumption. Consider the industrial temperature range variant if operating conditions exceed commercial limits. Verify interface compatibility with the target MAC layer devices using the PXPIPE specification.

Part Context

The PX1011B series consists of high-performance, low-power single-lane PCI Express PHYs designed for off-chip applications. It provides superior performance to Media Access Control (MAC) layer devices by handling low-level protocol and signaling tasks efficiently.

Replacement Considerations

Check for drop-in compatible alternatives within the same product family. Verify pinout and electrical specifications match exactly. Consult official substitution lists for confirmed equivalent part numbers.
