Need help with a VIP design like the C5G example

Hi,

that all depend son your system-settings.

You said, your Clocked-Video-Output runs at 44.8MHz. This is the outgoing clock of the CVO? So the CVO is configured with two clock domains? The (let's call it) Stream-Clock and the Video-Clock. Right?

What color plane setting do you have? All transmitted in parallel, or in sequence? What are the burst-settings of the Frame-Reader? How wide is the Frame-Reader-Memory-Interface and is it clocked with the DDR-Clock or with the Avalon-Clock?

The minimum frequency depends on the settings of the Color-Plane-Sequencer.

The only question I could answer without knowing more about your system-setup is the question regarding the clock domains:

-All IPs you connect with Avalon Stream, in your case the whole pipeline have to have the same clock for their streaming-ports. In your case variable is the Clock for the Memory-Interface of the Frame-Reader and the outgoing clock of the CVO.

So please give us more details on what you need, and what you have build yet.

Kind regards
