PX1012AI-EL1/G,551

Specialized Overview

The PX1012AI-EL1/G,551 is a high-performance, low-power, single-lane PCI Express electrical physical layer (PHY) designed for industrial applications. It handles the low-level PCI Express protocol and signaling, compliant with Base Specification Rev. 1.0a and 1.1. The device operates at a data rate of 2.5 Gbit/s and features an 8-bit parallel data interface operating at 250 MHz using SSTL_2 class I signaling. It includes clock and data recovery (CDR), serializer/deserializer (SerDes), 8b/10b encoding, and elastic buffer functions. The component supports power management states L0, L0s, and L1, dissipating less than 300 mW in normal mode. It operates within an ambient temperature range of -40 °C to +85 °C.

Specialized Feature Summary

• Compliant with PCI Express Base Specification 1.1, supporting single lane operation at 2.5 Gbit/s.
• Features an enhanced off-chip PXPIPE interface with source synchronous clocks for simplified timing closure.
• Includes advanced power management capabilities for L0, L0s, and L1 states with low jitter performance.
• Supports receiver detection, loopback modes, and lane polarity inversion for robust link training.

Specialized Applications

• Industrial systems requiring reliable PCI Express connectivity under wide temperature conditions.
• Embedded designs needing standalone X1 PHY solutions for FPGA or MAC integration.
• Equipment requiring low power consumption during idle or sleep states.

Specialized Procurement Notes

Verify the ordering suffix

Specialized Selection Notes

Select this model when industrial temperature stability (-40 °C to +85 °C) is required for PCI Express links. Ensure the design accommodates the specific voltage requirements: 3.3 V for JTAG/I/O, 2.5 V for SSTL_2, and 1.25 V for core logic. Confirm that the PCB layout supports the LFBGA81 package dimensions and ball mapping for proper signal integrity.

Specialized Part Context

This component belongs to the PX1011A/PX1012A family of standalone PCI Express PHYs originally developed by Philips Semiconductors. The 'I' suffix denotes the industrial temperature grade variant, while 'EL1/G' specifies the lead-free LFBGA81 packaging. It serves as a bridge between the MAC layer and the physical serial link, handling complex serialization tasks independently.

Specialized Replacement Considerations

The PX1011AI-EL1/G is the commercial-to-industrial counterpart within the same package and pinout. Cross-referencing with other standalone PCIe PHYs requires verifying compatibility with the proprietary PXPIPE interface extensions rather than standard PIPE specifications.
