What is the max pixel clock that the AVR32 can support on the ISI (Sensor) bus.

I'm looking at building a CMOS camera module, as well as a capture module, and want to make sure the timings match.

I dont expect the AVR to "capture" every frame, but I should be able to say every N frame.

It appears from timing, etc I should be able to use Micro 3 Megabit sensor(or highter), or a Tiple Video ADC such as the TDA8754.

Anyone have comments?

The isi mclk is connected to glck0, so you can generate any frequency that glck can. It is in other words dependant on the pll/osc settings for your system. You can choose to capture every n+1 frame. You will find the details on this in the register description for the isi moduke in the ap7000 datasheet.
