PX1012AI-EL1/G,557

Specialized Overview

The PX1012AI-EL1/G,557 is a high-performance, low-power single-lane PCI Express electrical PHY. It handles the low-level PCI Express protocol and signaling compliant with Base Specification Rev. 1.0a and 1.1. The device operates at 2.5 Gbit/s using an 8-bit data PXPIPE interface running at 250 MHz with SSTL_2 signaling. It includes clock and data recovery (CDR), serialization/deserialization, 8b/10b encoding, elastic buffers, and receiver detection. Designed for industrial applications, it supports power management states L0, L0s, and L1, dissipating less than 300 mW in normal mode.

Specialized Feature Summary

• Compliant with PCI Express Base Specification 1.1 supporting single lane operation
• Integrated clock and data recovery with serializer and de-serializer capabilities
• Supports advanced power management functions including L0, L0s, and L1 states
• Includes JTAG boundary scan interface with built-in self-test controller

Specialized Applications

• Industrial systems requiring robust PCI Express connectivity
• Embedded designs needing standalone X1 PHY solutions
• Equipment operating within extended temperature ranges

Specialized Procurement Notes

Verify the specific ordering suffix to confirm lead-free status and industrial temperature rating. Ensure compatibility with the target PCB footprint for the LFBGA81 package. Confirm that the supply voltage requirements align with the system design before procurement.

Specialized Selection Notes

Select this component when a standalone PCI Express PHY is required for single-lane applications. Consider the industrial temperature range if the environment exceeds commercial limits. Verify that the host MAC supports the PXPIPE interface for proper integration.

Specialized Part Context

This part belongs to the PX1011A/PX1012A family of PCI Express stand-alone X1 PHYs. It shares core functionality with the PX1011A but is distinguished by its industrial temperature rating and lead-free packaging options. The series provides a complete physical layer solution for PCI Express links.

Specialized Replacement Considerations

The PX1011AI-EL1/G is a compatible alternative within the same family offering identical performance with lead-free solder balls. Direct pin-to-pin replacement is possible provided the industrial temperature specification is met.
