PX1011BI-EL1/G,557

Specialized Overview

The PX1011BI-EL1/G,557 is a single-lane PCI Express electrical PHY compliant with Base Specification Rev. 1.0a and 1.1. It operates at 2.5 Gbit/s using an 8-bit PXPIPE interface running at 250 MHz with SSTL_2 signaling. The device supports industrial temperature range (-40°C to +85°C) and dissipates less than 300 mW in L0 mode. Key features include Clock and Data Recovery (CDR), 8b/10b encoding, elastic buffer, receiver detection, and JTAG boundary scan. Power supplies are 3.3 V for JTAG/I/O, 2.5 V for SSTL_2, and 1.2 V for core/high-speed I/O.

Specialized Feature Summary

• Compliant with PCI Express Base Specification 1.1
• Supports advanced power management states including L0, L0s, and L1
• Includes built-in self-test controller for SerDes and I/O blocks
• Features source synchronous clocking for simplified timing closure

Specialized Applications

• PCI Express link implementations requiring standalone PHY solutions
• ASIC prototyping and FPGA-based products
• Industrial applications requiring extended temperature operation

Specialized Procurement Notes

Verify the ordering suffix 'G' indicates lead-free packaging with SnAgCu solder balls. Confirm the 'I' suffix denotes the industrial temperature range of -40°C to +85°C. Ensure the '557' reel quantity matches specific procurement requirements. Cross-reference the package type LFBGA81 with PCB footprint designs.

Specialized Selection Notes

Select this component when a standalone PCIe PHY is required for off-chip integration with MAC layers. The PXPIPE interface provides enhanced synchronization compared to standard PIPE. Consider the industrial rating if ambient temperatures exceed commercial limits. Verify voltage domain compatibility between the 2.5 V SSTL_2 interface and the host MAC.

Specialized Part Context

This part belongs to the NXP PX1011B family of PCI Express PHYs. Variants include commercial temperature versions and automotive AEC-Q100 compliant models. The PX1011BI-EL1/G,557 specifically targets industrial environments with lead-free manufacturing processes.

Specialized Replacement Considerations

Direct substitutes within the same package and specification include PX1011B-EL1/G for commercial temperature ranges. Automotive variants like PX1011B-EL1/Q900 offer AEC-Q100 compliance but require separate qualification verification.
