Hi TI team.
I have a question.
Can I use clk_out signal(Pin No.19) of DS90BU953 for CIS input clk ?
I tested this connection and checked no issue on camera operating.
If it is fine, the design is better for cost reduction.
But I concern what side-effect occur because it is for automotive.
We need to satisfy many of reliability test.
Which design is better for automotive camera ?
Add external oscillator or not use.
I'll be waiting for your answer.
Thank you !
Hi Hamzeh,
I draw some block diagram in detail.
It is for e-Mirror camera solution.
XVCLK is mean main master clock of Image sensor.
I found some formula in Ser datasheet.
And I set the register as below table.
| F (MHz) | 25 |
| HS_CLK_DIV | 4 |
| M | 1 |
| N | 42 |
| CLK_OUT (MHz) | 23.80952381 |
The camera oscillator was removed and tested with the above setting, and there was no abnormality.
Can I use CLK_out from the serializer as the main clock of the camera without an external oscillator?
