PX1011B-EL1/N,551

Overview

The PX1011B-EL1/N,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 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. It supports power management states L0, L0s, and L1, dissipating less than 300 mW in normal mode. Operating temperature range is commercial (0°C to +70°C).

Feature Summary

• Compliant with PCI Express Base Specification 1.1 for single lane operation.
• Includes integrated Clock and Data Recovery (CDR) and Serializer/Deserializer (SerDes).
• Supports advanced power management functions including L0, L0s, and L1 states.
• Features JTAG boundary scan interface with Built-In Self Test (BIST) controller.

Applications

• PCI Express link interfaces requiring standalone X1 PHY solutions.
• Systems utilizing FPGA products compatible with SSTL_2 I/O interfaces.
• Industrial applications requiring commercial temperature range operation.

Procurement Notes

Verify the ordering suffix 'N' indicates SnPb solder ball compound and leaded package construction. Confirm the specific revision level matches design requirements. Ensure compatibility with the host MAC's PXPIPE implementation. Check that the commercial temperature rating meets system environmental specifications.

Selection Notes

Select this component for designs requiring a standalone PCIe Gen 1 PHY. Verify voltage levels match the target SSTL_2 class I signaling requirements. Ensure the LFBGA81 package fits the PCB layout constraints. Consider the industrial variant if extended temperature ranges are necessary.

Part Context

This part belongs to NXP's PCI Express PHY portfolio. It serves as a physical layer transceiver for high-speed serial communication. The device bridges the gap between the MAC layer and the physical connector. It enables reliable data transmission over differential pairs.

Replacement Considerations

PX1011B-EL1/G: Lead-free version of the same functional device. PX1011BI-EL1/G: Industrial temperature range variant. PX1011B-EL1/Q900: Automotive AEC-Q100 compliant version.
