Menu
This menu configures the push buttons to cycle through supported clock frequencies. Users must select a video
format with a compatible frequency in order for the system to be configured. If the system is in Standalone Mode
and a valid combination is selected, the LEDs will flash once to indicate successful configuration. In other mode
the video format and frequency settings are ignored.

Figure 23) Video Format and Clock Frequency Table
Depending on the format the frequency specified in Figure 22 can refer to either the field or frame rate. For
interlaced images it is the field rate and for progressive and segmented frame it is the frame rate.

FPGA Register Map
This section describes the registers associated with the SDI Video Firmware. Registers can be either status or
control, and are read or write respectively. The registers are grouped into several main sections:
1. Miscellaneous
2. Reset
3. Rx
Video
4. Datapath
5. Clocking
6. Timing
