PX1011A-EL1:557

Overview

The PX1011A-EL1:557 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 parallel data interface running at 250 MHz with SSTL_2 signaling. The device includes clock and data recovery, 8b/10b encoding, and elastic buffering. It supports power management states L0, L0s, and L1, dissipating less than 300 mW in normal mode. The component utilizes a 9x9 mm LFBGA81 package and accepts a 100 MHz reference clock with ±300 ppm tolerance.

Feature Summary

• Compliant with PCI Express Base Specification 1.1 for single lane operation
• PXPIPE interface adapted for off-chip applications with source synchronous clocks
• Integrated clock and data recovery with low jitter performance
• Supports advanced power management including L0, L0s, and L1 states

Applications

• PCI Express link implementations in FPGA-based designs
• ASIC prototyping requiring external PHY solutions
• System-on-Chip designs utilizing the PXPIPE PHY interface standard

Procurement Notes

Verify the specific ordering suffix to confirm lead-free status and temperature range. The EL1 designation indicates the LFBGA81 package variant. Ensure compatibility with the required solder process, as Pb-free and SnPb versions exist within the same family. Confirm availability through authorized distributors as this component may be subject to end-of-life policies.

Selection Notes

Select the PX1011A-EL1/G variant for lead-free manufacturing requirements. Choose the industrial temperature grade if operation below 0°C is necessary. Ensure the design supports the 2.5 V SSTL_2 I/O voltage level and provides the required 100 MHz reference clock input. Verify that the MAC layer supports the PXPIPE interface protocol for proper integration.

Part Context

This component belongs to the NXP PCI Express PHY family, designed to complement digital controllers like Synopsys DesignWare IP. It serves as a standalone physical layer solution for systems requiring PCIe connectivity without integrated PHYs. The PX1011A is optimized for low-cost FPGAs and ASICs, providing a proven alternative to internal PHY implementations.

Replacement Considerations

The PX1012A is a compatible part number within the same series. Both devices share identical packaging and interface specifications. Verify functional equivalence regarding pinout and signaling before substitution.
