PX1011B-EL1/Q900'5

Overview

The PX1011B-EL1/Q900'5 is an automotive-grade, single-lane PCI Express electrical PHY compliant with Base Specification Rev. 1.0a and 1.1. Operating at 2.5 Gbit/s, it features a 250 MHz 8-bit PXPIPE interface using SSTL_2 signaling. It includes Clock and Data Recovery (CDR), 8b/10b encoding, and elastic buffering. The device dissipates less than 300 mW in L0 mode and supports power states L0, L0s, and L1. It operates within the industrial temperature range of -40°C to +85°C and utilizes an LFBGA81 package.

Feature Summary

• Compliant with PCI Express Base Specification 1.1 for single lane operation
• Includes Clock and Data Recovery (CDR) and 8b/10b encoding/decoding
• Supports advanced power management for L0, L0s, and L1 states
• Automotive AEC-Q100 compliant version available

Applications

• PCI Express link interfaces in automotive systems
• Industrial applications requiring extended temperature ranges
• FPGA-based designs needing standalone PCIe PHY support

Procurement Notes

Verify that the specific suffix Q900 indicates the Automotive AEC-Q100 compliant variant as documented in the datasheet. Confirm the solder process matches the required Pb-free SnAgCu compound associated with this ordering code. Ensure the application environment falls within the specified industrial temperature limits of -40°C to +85°C.

Selection Notes

Select this component when a standalone PCIe PHY is required for FPGA integration. The PXPIPE interface simplifies timing closure compared to standard PIPE specifications. Consider the automotive qualification if the deployment requires AEC-Q100 compliance. Verify voltage requirements for VDDD1, VDDD2, and core supplies before design finalization.

Part Context

This part belongs to the PX1011B family of single-lane PCIe PHYs from NXP Semiconductors. It serves as a bridge between MAC layers and physical media. The Q900 suffix specifically denotes the automotive grade version, distinguishing it from commercial or standard industrial variants like the PX1011BI.
