F and V change state at the EAV sequence at the beginning of the digital line. Note that the digital line number changes state prior to the start of horizontal sync, as shown in Figures 7.3-32 and 7.3-33. Note that square pixels and a 16:9 aspect ratio are Example relationships between the analog and digital used. Other common active resolutions, their 1 X Y and signals are shown in Figures 7.3-35 and 7.3-36, and Table R'G'B' sample rates (Fs), and frame rates, are: 7.3-3.
