Hi,
I'm using the Intel i7 processor CSI-2 interface to read the serial output data from ADV7280A-M chip.
So far, I was successful with the ADV7280A-M control through I2C port. However, I'm facing several issues reading the CSI-2 output.
I need to configure the following registers in the intel processor to correctly receive the serial output data from the ADV7280A-M chip.
- Clock termination delay
- Clock settling delay
- Data termination delay
- Data setting delay
To compute all these values, I need to know the MIPI bus frequency in hertz.
I looked at the ADV7280A-M documentation and I was not able to find the CSI-2 output frequency.
Could you please help with the frequency (in Hz) that the data is transmitted from the ADV7280A-M chip?
Thanks,
Anand
Hi,
The data rates are fixed depending on the mode of operation.
In interlaced mode the ADV7282-M outputs with a 216 Mbps data rate (MIPI clock frequency 108 MHz).
In progressive mode (i.e. I2P mode on) the ADV7282-M outputs a 432 Mbps data rate ( MIPI clock frequency 216 MHz).
Also Expert written an apps note to help customer interface the ADV7282-M with MIPI receivers. AN-1337 is available at AN-1337
Thanks,
