Hi all, I’m very new to working with MIPI CSI2. I’ve searched around for the answer to this, but haven’t been able to get far without access to MIPI specifications — apologies if these turn out to be very basic questions.
I’m designing for an Omnivision image sensor. I can’t share the datasheet or specific details, unfortunately, since it’s confidential with Omnivision.
The chip uses a single-lane MIPI data output. The D-PHY connector on the Raspberry Pi is for 2-lane MIPI data transfer.
Can I simply connect the sensor data output to one lane of the Raspberry Pi, leaving the other Pi lane disconnected? And would doing so require any special drivers? Or alternatively, would I need to use some kind of MIPI receiver/decoder to convert to a different protocol that the microcontroller can receive?
Further, are MIPI voltage levels standardized? The chip I’m using has a 1.5 V MIPI voltage supply.
I’m hoping to use an FSA641 MIPI bridge (unless anyone has a better suggestion for receiving data from multiple cameras). A diagram from the bridge datasheet would seem to indicate that the single-lane and dual-lane are compatible in this direction, but this may be misleading.
Thank you in advance for the help!
