i need making converter from to
hdmi to composite and composite to hdmi circuit and file
what ics i used and need circuit
For HDMI -> composite you will have to use something a long the lines of the ADV7842 plus ADV7393
For Composite -> HDMI you can use an ADV7850 or ADV7842 plus ADV7511
What format video do you want to work with and are there any other constraints / requirements?
Here is a list of recommended components
hi thank you i need hdmi any format like 1920 *1080 to composit d1 format working in normal crt tv \
First of all I am going to assume your video is 1080i input not 1080p.
For HDMI -> composite I would start with a ADV7612-P plus ADV7393 combination. The 7612 will receive the HDMI and convert it to a BT.656 digital format. The 7393 will convert the BT.656 digital video to analog composite output.
For composite -> HDMI I would start with theADV7181D to digitize the analog video to BT.656 and maybe the ADV7511 for the transmitter
Be careful with what parts you select. Unless you are an HDCP adopter we can not sell you a HDMI receiver with HDCP keys. Some receivers are keyless such as the ADV7612-P part
