PX1011B-EL1/G,551

Overview

The PX1011B-EL1/G,551 is a single-lane PCI Express electrical PHY compliant with Base Specification Rev. 1.0a and 1.1. It operates at 2.5 Gbit/s using an 8-bit PXPIPE interface running at 250 MHz with SSTL_2 signaling. The device includes Clock and Data Recovery (CDR), 8b/10b encoding, and elastic buffering. Power consumption is under 300 mW in L0 mode. It supports commercial (0°C to +70°C) and industrial (-40°C to +85°C) temperature ranges. 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 (CDR) with low jitter performance
• Supports advanced power management states including L0, L0s, and L1
• Includes JTAG boundary scan interface with Built-In Self Test (BIST)

Applications

• PCI Express link interfaces in FPGA-based designs
• High-speed serial data transmission systems
• Industrial embedded communication modules

Procurement Notes

Verify the specific ordering suffix matches the required solder process and temperature grade. Confirm that the 'G' designation corresponds to the Pb-free SnAgCu solder ball compound. Ensure the quantity aligns with standard supplier packaging configurations. Cross-reference the part number against current NXP availability status prior to finalizing procurement orders.

Selection Notes

Select this component when a standalone PCIe PHY is required for off-chip integration with MAC devices. The PXPIPE interface simplifies timing closure compared to standard PIPE specifications. Consider the industrial temperature variant if operating environments exceed commercial limits. Verify voltage domain compatibility between the 2.5V SSTL_2 I/O and the host system logic levels.

Part Context

This component belongs to the PX1011 family of high-performance, low-power PCI Express PHYs. It is designed to handle low-level protocol and signaling tasks, allowing the connected MAC to focus on higher-layer processing. The series offers flexibility for various applications requiring reliable serial connectivity.

Replacement Considerations

The PX1011B-EL1/N serves as the leaded solder alternative to the Pb-free EL1/G version. Both share identical functional specifications and pinouts within the LFBGA81 package. Select based on manufacturing assembly requirements regarding lead content regulations.
