Hi David,

The schematic for the TS#DV642 looks correct!

I will actually forward this thread to a team internal to TI who are experts with the SN65 device.

Regards,

Kameron

HI Aaron Heng

1. I can't see the 2-point text on U26 in the attached circuit.(Text in parts R338 and R339 is not visible.)

2. I2C is connected to the AP terminal with a 2.2K ohm Pull up.

3. The device TS3DV642RUATQ1 is connected to SN65DSI83 and SN65DSI86.

4. Added 100nF to each power terminal of U27.

Hi Ohoon,

The R338 is series with EN pin. I would recommend to add 10uF instead of 220pF. The R339 if you are planning to use DSI clock you need to short REFCLK pin to ground with a series resistor.

Thank you for confirming 2-3 points.

Aaron
