Design Notes
- MS2108 targets parallel digital video input. Confirm target bus width, timing format, pixel clock, and synchronization mode during design.
1920 x 1080 @ 30Hzoutput usually depends on MJPEG mode. YUV output capability should be validated against USB2.0 bandwidth and host performance.- Parallel video uses many data lines, so PCB design should account for clock routing, data-line length matching, crosstalk, and input timing margin.
