How to support composite video output on AM18xx

Dear Experts

My customer want to find a low-cost MPU which can support composite video output.

But according to the spec, it seesm Sitara AM18xx serial does not build in composite video DAC.

Am I right?

Thanks a lot.

    This does seem to be the case, so you would need an external video encoder (DAC) to generate a composite output. TI does not provide such devices so this would be from another silicon vendor, in the past we have used parts like Phillips SAA7105 and ADI ADV7343 to handle this sort of conversion on EVMs for devices that do not have integrated video DACs.

    One alternative TI does have that offers a fairly low cost MPU with integrated video DACs for composite output would be the DM335.
