PX1011B-EL1/N,557

Overview

The PX1011B-EL1/N,557 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 (CDR), 8b/10b encoding, and elastic buffering. Supply voltages are 3.3 V for JTAG I/O, 2.5 V for SSTL_2 I/O, and 1.2 V for the core and high-speed serial pads. It supports LFBGA81 packaging and functions within a commercial temperature range of 0 °C to +70 °C.

Feature Summary

• Compliant with PCI Express Base Specification 1.1 for single lane operation
• Includes Clock and Data Recovery (CDR) and 8b/10b coding
• Supports advanced power management states including L0, L0s, and L1
• Features JTAG boundary scan interface with Built-In Self Test

Applications

• PCI Express link interfaces in industrial systems

• Low jitter signal integrity applications requiring receiver detection

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and solder process compatibility. Confirm that the component meets the required environmental specifications for the intended deployment environment before finalizing procurement decisions.

Selection Notes

Select this component when a standalone PCIe PHY is required for a single-lane configuration. Ensure the design accommodates the necessary voltage domains and utilizes the PXPIPE interface. Verify that the operating temperature range aligns with the system's thermal requirements.

Part Context

This part belongs to the PX1011B family of PCI Express PHYs manufactured by NXP Semiconductors. It serves as a physical layer transceiver designed to handle low-level protocol signaling. The EL1 suffix indicates the leaded solder ball compound variant within the LFBGA81 package family.

Replacement Considerations

The PX1011B-EL1/G is the lead-free equivalent offering identical functionality. The PX1011BI-EL1/G provides industrial temperature range capabilities. The PX1011B-EL1/Q900 is available for automotive AEC-Q100 compliance requirements.
