SN65DSI84: Questions of SN65DSI84

Jimmy

Can you please share the video panel spec? 

What is the DSI_CLK frequency you are using? And are you following the right power sequence as specified in Table 7-2 of the datasheet? 

When switching from reference clock to DSI CLOCK, did you toggle PLL_EN and then the SOFT_RESET bit? 

We typically recommend people to use reference clock instead the DSI CLK as the reference clock tends to provide a cleaner clock than the DSI CLK.

Thanks

David

Hi David,

What is the DSI_CLK frequency you are using? And are you following the right power sequence as specified in Table 7-2 of the datasheet?

[Ans]
1. soft reset bit 0x09 as 1
2. set 0x0D as 0
3. config DSI clock
4. set 0x0D as 1

Many Thanks,

Jimmy

Have you used DSI Tuner to generated the DSI CLK? And does the test pattern work? 

3554.DSI Tuner 2.1.zip

When in DSI CLK, can you please probe the DSI CLK and verify the DSI CLK is in HS continuous mode?

Thanks

David

Hi David,

Thanks a lot. 

Is this tool to be tested with EVB?

Currently, it is possible to use the reference clock, but is it necessary to measure the dsi clock?

Many Thanks,

Jimmy
