When designing for the PCB, refer to Video PHY Controller LogiCORE IP Product Guide (PG230) for pin outputs to the PCB from the PHY. This section discusses the I/O pins of the subsystem and external IC/PCB considerations.
I/O Pins
-
aux_rx_data_out -
aux_rx_data_en_out_n -
aux_rx_data_in -
ext_iic -
rx_hpd
The aux_* and hpd signals are sent through a level shifter, such as the
SN74AVC4T774, followed by a line driver, such as the SN64MLVD2020A, and then an RC
circuit before the rx_out and rx_in signals are connected to SBU1 and SBU2 (P/N) of
the MCDP6000. The ext_iic lines are connected to
the SCL/SCA lines of the MDCP6000.
PHY Pins
The following pins are detailed in Video PHY Controller LogiCORE IP Product Guide (PG230).
-
link_rx_lane_n[x:0] -
link_rx_lane_p[x:0]
The following DisplayPort link pins are connected to the MCDP6000 RX and TX pins. For more details, see the MCDP6000 documentation.
-
link_rx_lane_n[0]toRX1n -
link_rx_lane_n[1]toTX1n -
link_rx_lane_n[2]toTX2n -
link_rx_lane_n[3]toRX2n
