PX1011AI-EL1/G,551

Overview

The PX1011AI-EL1/G,551 is a single-lane PCI Express electrical PHY compliant with Base Specification Rev. 1.1. It operates at 2.5 Gbit/s using an 8-bit parallel data interface (PXPIPE) running at 250 MHz with SSTL_2 signaling. The device includes clock and data recovery, serializer/deserializer, and 8b/10b encoding. It supports industrial temperature range (-40 °C to +85 °C). Power consumption is under 300 mW in normal mode. Supply voltages include 3.3 V for JTAG/I/O, 2.5 V for SSTL_2, 1.25 V for core, and 1.2 V for high-speed serial I/O.

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

Applications

• PCI Express link interfaces requiring standalone PHY solutions
• Industrial systems operating within extended temperature ranges
• FPGA-based designs utilizing source synchronous clocking

Procurement Notes

Verify the ordering suffix matches the required lead-free solder process and industrial temperature rating. Confirm package dimensions against the LFBGA81 specification. Ensure supply voltage levels align with system design requirements before procurement.

Selection Notes

Select this component when a dedicated PCI Express physical layer is needed separate from the MAC logic. Consider the PX1011A variant for commercial temperature applications if industrial ratings are not required. Verify compatibility with the target FPGA or controller's PIPE interface implementation.

Part Context

This part belongs to the PX1011A/PX1012A family of PCI Express PHYs. The PX1012A variant offers dual-lane support compared to the single-lane PX1011A. Both families share similar architectural features and interface standards.
