PCI Express x1 PHY single-lane transceivers

For applications that use an ASIC or a low-cost FPGA to implement the MAC portion of the PCI Express protocol, NXP Semiconductors offers our PX1011 2.5-Gbps PCI Express PHY transceivers with 8-bit data PXPIPE interfaces. Available in very small, leaded and lead-free LFBGA-81 packages that measure only 9 x 9 x 1.05 mm, they offer features that ease layout, improve performance, and increase design flexibility.

NXP Semiconductors is the first discrete PCI Express PHY vendor to pass the PCI-SIG compliance tests. NXP Semiconductors has worked with multiple partners to perform comprehensive tests in multiple PC systems to ensure interoperability, compliance, and excellent throughput.

Fast, low-risk digital ASIC designs

Our PX1011 products makes ASIC development faster and less risky. By isolating the mixed-signal PHY functions in an external transceiver, they let the ASIC's digital functions migrate to the latest process technologies without impacting complex PHY operations.

Increased efficiency of low-cost FPGA designs

Low-cost, high-density FPGAs don't typically offer an on-chip PHY or SERDES. PX1011 products let designers use an inexpensive FPGA to create low-cost, flexible PCI Express applications that have customer-specific functions coded into the FPGA. The result is greater differentiation in a format that is easily scalable to high-volume, consumer-oriented applications.

Tiny package optimized for PCB layout

Our PX1011 PHYs come in the industry's smallest package, the LFBGA-81. Despite its tiny size, we have optimized the ease of layout by having 2 signal rings, thus requiring only two signal layers in the PCB design.
