Other Parts Discussed in Thread: SN65DSI84-Q1

Hi,

I have a question about "SN65DSI83-Q1" and "SN65DSI84-Q1".

Is it possible to convert MIPI parallel inputs (2 lanes) to LVDS parallel outputs (4 lanes)?

Our customer wants the LVDS module to output characters. Since the CPU outputs MIPI, conversion is required.

Best Regards,

Nishie

Hi Nishie,

Yes, but it depends on the DSI CLK frequency required to support the target resolution. Check the DSI CLK equation in the 1st post in this FAQ: https://e2e.ti.com/support/interface-group/interface/f/interface-forum/945185/faq-sn65dsi84-sn65dsi83-sn65dsi84-and-sn65dsi85-resolution-guide

Hi, I.K.,

I have an additional question.

I plan to use 2 lanes (DA0P / N and DA1P / N) for MIPI input.

Should unused 2 lanes (DA2P / N and DA3P / N) be connected to GND or OPEN?

Best Regards,

Nishie

Hi Nishie,

Unused DSI lanes should be left open.
