AM3352: PCIe device connection

Part Number: AM3352
Other Parts Discussed in Thread: XIO1100

Hello TI guys:

There is a communication card with pcie interface in our project .

however ,there is no pcie on am335x.

Is that possible to  connect the XIO1100  pcie mac to the gpmc of am335x to access the pcie card?

Best regards

  • Hi,

    On the processor side XIO1100 uses a TI-PIPE interface, which 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. Both buses are clocked using Single Data Rate (SDR) clocking in which the data transitions are on the rising edge of the associated clock.
    • The 8-bit TI-PIPE interface is a 250 MHz 8-bit parallel interface with an 8-bit output bus (RXDATA) that is clocked by the RXCLK output clock and an 8-bit input bus (TXDATA) that is clocked by the TXCLK input clock. Both buses are clocked using Double Data Rate (DDR) clocking in which the data transitions are on both the rising edge and the falling edge of the clock.

    Neither of these interfaces can be connected to the GPMC interface available on AM335x devices.

  • Hi Biser:

    So Is there any way to connect the pcie card using am335x?

    Best regards

  • There may be third-party solutions, that I don't know about. Another possibility is through an FPGA.
