PX1011A-EL1/G,557

Overview

The PX1011A-EL1/G,557 is a single-lane PCI Express electrical physical layer (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 integrates clock and data recovery (CDR), serializer/deserializer (SerDes), 8b/10b encoding, and elastic buffering. It supports industrial temperature range operation from -40 °C to +85 °C. Power consumption in normal mode is less than 300 mW. The component utilizes a lead-free LFBGA81 package.

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 with built-in self-test capabilities

Applications

• PCI Express link interfaces requiring standalone PHY implementation
• Industrial systems operating within extended temperature ranges
• Hardware designs utilizing FPGA or MAC devices with PXPIPE compatibility

Procurement Notes

Verify the ordering suffix matches the required solder process and environmental rating. The '/G' designation indicates a lead-free variant using SnAgCu solder ball compound. Confirm the specific tape and reel quantity associated with the ',557' suffix against manufacturer documentation prior to acquisition.

Selection Notes

Select this component when a standalone PCIe PHY is required for a single-lane configuration. Ensure the host system provides a 100 MHz reference clock with ±300 ppm tolerance. Verify that the design accommodates the necessary voltage domains: 3.3 V for JTAG/I/O, 2.5 V for SSTL_2, and 1.25 V for core operations.

Part Context

This part belongs to the PX1011A/PX1012A family of high-performance, low-power PCI Express PHYs. The PX1011A variant specifically supports a single lane, whereas the PX1012A supports dual lanes. Both share similar architectural features and interface protocols.
