TVP5146 and two cameras

Other Parts Discussed in Thread: DM3730, OMAP3530, TVP5146

Hi folks,

I'm starting a new project that needs two cameras connected on ARM. Probably I will use OMAP3530 or DM3730.

I will use the TVP5146 and the cameras with composite signal.

My doubt is about the driver for TVP5146. Can the actually driver configure the chip for two composite video input?

I hear some things about the driver has limited resources and maybe couldn't to do that.

Anybody here did something like that?

Thank you.

    Hi Claudio,

    Both processors OMAP3530 and DM3730 support two camera input streams but there are some limitations:

    By configuring the outside PHYs and feeding the receivers, the camera ISP supports up to two simultaneous pixel flows from external sensors. Only one of the data flow can use the Video processing hardware while the other must go to memory.

    You could read more details in the Camera ISP overview chapter in the Technical reference manual:
