XIO1100,pdf(Data Manual)

The XIO1100 is a PCI Express™ PHY that is compliant with PCI Express Base Specification Revision 1.1 and that interfaces the PCI Express Media Access Layer (MAC) to a PCI Express serial link by using a modified version of the interface described in PHY Interface for the PCI Express™ Architecture (also known as PIPE interface) by Intel Corporation. This modified version of the PIPE interface is referred to as a TI-PIPE interface throughout this data manual.

The TI-PIPE interface is a pin-configurable interface that can be configured as either a 16-bit or an 8-bit interface.

• The 16-bit TI-PIPE interface is a 125 MHz 16-bit parallel interface with a 16-bit output bus (RXDATA) that is clocked by the RXCLK output clock and a 16-bit input bus (TXDATA) that is clocked by the TXCLK input clock.
