SN65DSI83: does it use in sync with the MIPI interface clock?

Part Number: SN65DSI83

If an external reference clock is not used,
that is, if the REFCLK@H2 pin is pulled to GND with an external resistor,
does it use in sync with the MIPI interface clock (DACN@J5pin / DACP@H5pin)?

Hi Sakai-san,

The DSI clock will be used regardless of whether or not the REFCLK is used. The REFCLK is only optionally used to source the PLL and generate the output LVDS clock.

Dear I.K.

Thank you for your reply.

I have questions.

Q1
Does the DSI clock mean DAC(DACN@J5pin / DACP@H5pin)?

Q2
Does the LVDS clock mean A_CLK(A_CLKN@F9 A_CLKP@F8)?

Q3
If an external reference clock is not used,
Are DAC(DACN@J5pin / DACP@H5pin) and A_CLK(A_CLKN@F9 A_CLKP@F8 in sync?

Hi Sakai,

1. Yes

2. Yes

3. The DSI CLK is used internally to generate the LVDS CLK if an external REF CLK is not used. Please see section 7.3.1 of the datasheet for details
