PX1012A-EL1/G,557

Specialized Overview

The PX1012A-EL1/G,557 is a single-lane PCI Express electrical PHY manufactured by NXP USA Inc. It operates at 2.5 Gbit/s and complies with PCI Express Base Specification Rev 1.0a and 1.1. The device features an 8-bit parallel data interface operating at 250 MHz using SSTL_2 signaling. It includes clock and data recovery (CDR), serializer/deserializer (SerDes), and 8b/10b encoding. The component supports industrial temperature ranges from -40 °C to +85 °C and dissipates less than 300 mW in normal mode.

Specialized Feature Summary

• Compliant with PCI Express Base Specification 1.1 for single lane operation
• Integrated clock and data recovery with low jitter performance
• Supports advanced power management states including L0, L0s, and L1
• Includes JTAG boundary scan interface for built-in self-test

Specialized Applications

• PCI Express link interfaces requiring standalone PHY solutions
• Industrial systems requiring extended temperature range operation
• Hardware designs utilizing FPGA or MAC devices with PIPE-compatible interfaces

Specialized Procurement Notes

Verify the specific ordering suffix against current manufacturer documentation to confirm lead-free status and package variant. Confirm availability as this component may be subject to discontinuation notices. Ensure compatibility with existing PCB footprints and soldering processes before finalizing procurement orders.

Specialized Selection Notes

Select this component when a dedicated single-lane PCIe PHY is required for off-chip applications. Ensure the design accommodates the specific voltage requirements for VDDD1, VDDD2, and VDDD3 supplies. Verify that the host MAC supports the enhanced PXPIPE interface with source synchronous clocks for proper timing closure.

Specialized Part Context

This part belongs to the PX1011A/PX1012A family of high-performance, low-power PCI Express PHYs. These components are designed to handle the physical layer protocol and signaling independently from the Media Access Control (MAC) layer. The series provides superior performance through integrated analog buffers and elastic buffers.
