2.1 Board Setup

This section describes how to quickly set up the DS90UH928QEVM with an appropriate serializer for evaluation of the chipset in display applications. The default switches and jumper positions have been set at the factory. This setup guide assumes the user has already installed and configured the included ALP software. See Installation for details.

  1. Connect an appropriate 12 VDC power supply to barrel jack J12. If 1.8V VDDIO operation is desired, set the 1.8V position at JP10.
  2. Connect an applicable cable (not provided, HSD automotive connector configured by default) from the DS90UH928QEVM (RX) board FPD-Link III input (J4) to the FPD-Link III output of a compatible FPD-Link III (TX) board (DS90UB925-Q1EVM or DS90UH927QEVM).
  3. From the Video source, connect a flat cable to the TX board (J5) and connect the appropriate cable from the RX board to the panel.
  4. Connect the included USB cable from a host computer running the included TI ALP software to the USB port (J17) on the RX board. See Usage for further information on using the TI ALP tool.
  5. (Optional) Connect audio from an I2S audio source to TX board (JP2) pins DA (data), CLK (clock), and WC (word clock) and from RX board pins DA, CLK, and WC to an I2S DAC.
  6. (Optional) Connect and configure any required GPIO interfaces. GPIO0 and GPIO1 are dedicated pins.

Jumpers and switches have been configured by TI and do not require any changes for immediate operation of the board. See Evaluation Hardware Overview and the DS90UH928Q device data sheet for further details.
