A video transfer circuit includes: a first communication interface; a second communication interface; and a digital timing generator having an input, an output, and a video timing signal interface. The input is coupled to the first communication interface. The video timing signal interface is coupled to the second communication interface. The digital timing generator is configured to: provide a first video timing signal to the second communication interface via the video timing signal interface responsive to a first mode selection; and receive a second video timing signal from the second communication interface via the video timing signal interface responsive to a second mode selection.

Video transfer circuit with multi-chip synchronization circuitry

In an example, a circuit includes a differential input circuit having a first input at a first capacitor terminal and a second input at a second capacitor terminal. The differential input circuit includes a first transistor having a first transistor control terminal and first and second terminals. The differential input circuit includes a second transistor having a second transistor control terminal and first and second terminals, the first terminals of the first and second transistors coupled together. The circuit includes a first capacitor having the first capacitor terminal and having another terminal coupled to the first transistor control terminal. The circuit also includes a second capacitor having the second capacitor terminal and having another terminal coupled to the second transistor control terminal. The circuit includes a first offset correction input coupled to the first transistor control terminal and a second offset correction input coupled to the second transistor control terminal.
