Abstract
A vertical synchronization circuit for synchronizing multiple video streams using an input vertical sync signal. The circuit includes a digital phase lock loop circuit configured to generate an intermediate frequency signal based on the input vertical sync signal and an analog phase lock loop circuit configured to convert the intermediate frequency signal into a pixel clock. They system further includes a counter configured to generate output synchronization signals based on the pixel clock.
