AUX Channel - 2.1 English

The VESA DisplayPort Standard describes the AUX channel as a bidirectional LVDS signal. For 7 series designs, the core uses IOBUFDS (bidirectional buffer) as the default with the LVDS standard. You should design the board as recommended by the VESA DP Protocol Standard. For reference, see the example design XDC file.

For AMD Kintex™ 7 devices supporting HR IO banks, use the following constraints:

For Source:

set_property IOSTANDARD LVDS_25           [get_ports aux_tx_io_p]

set_property IOSTANDARD LVDS_25           [get_ports aux_tx_io_n]

For Sink:

set_property IOSTANDARD LVDS_25           [get_ports aux_rx_io_p]

set_property IOSTANDARD LVDS_25           [get_ports aux_rx_io_n]

For AMD Kintex™ 7 and AMD Virtex™ 7 devices supporting HP IO banks, use the following constraints:

For Source:

set_property IOSTANDARD LVDS                            [get_ports aux_tx_io_p]

set_property IOSTANDARD LVDS                            [get_ports aux_tx_io_n]

For Sink:

set_property IOSTANDARD LVDS                           [get_ports aux_rx_io_p]

set_property IOSTANDARD LVDS                           [get_ports aux_rx_io_n]
