Description
PCI Express stand-alone X1 PHY Receiver detection
Manufacturer
NXP [NXP Semiconductors]
Datasheet
1. General description
2. Features and benefits
2.1 PCI Express interface
2.2 PHY/MAC interface
The PX1011B is a high-performance, low-power, single-lane PCI Express electrical
PHYsical layer (PHY) that handles the low level PCI Express protocol and signaling. The
PX1011B PCI Express PHY is compliant to the PCI Express Base Specification,
Rev. 1.0a, and Rev. 1.1. The PX1011B includes features such as Clock and Data
Recovery (CDR), data serialization and de-serialization, 8b/10b encoding, analog buffers,
elastic buffer and receiver detection, and provides superior performance to the Media
Access Control (MAC) layer devices.
The PX1011B is a 2.5 Gbit/s PCI Express PHY with 8-bit data PXPIPE interface. Its
PXPIPE interface is a superset of the PHY Interface for the PCI Express (PIPE)
specification, enhanced and adapted for off-chip applications with the introduction of a
source synchronous clock for transmit and receive data. The 8-bit data interface operates
at 250 MHz with SSTL_2 signaling. The SSTL_2 signaling is compatible with the I/O
interfaces available in FPGA products.
The PX1011B PCI Express PHY supports advanced power management functions. The
PX1011BI is for the industrial temperature range (−40 °C to +85 °C).

Supports loopback
Supports direct disparity control for use in transmitting compliance pattern
Supports lane polarity inversion
Low jitter and Bit Error Rate (BER)
Based on Intel PHY Interface for PCI Express architecture v1.0 (PIPE)
Adapted for off-chip with additional synchronous clock signals (PXPIPE)
8-bit parallel data interface for transmit and receive at 250 MHz
2.5 V SSTL_2 class I signaling
