Figure 3. Group Delay, all Outputs
Low frequency group delay is 62ns. At 3.58MHz group
delay increases by only 4ns. At 4.43MHz group delay
increases by only 7ns. The maximum deviation from flat
group delay of 12ns occurs at 6MHz.
Figure 4. DC Restore Performance of Luma Output
Luma ramp test pattern is shown to have minimal tilt
during vertical sync.
In most applications, the ML6428's input coupling
capacitors are 0.1µF. The Y input sinks 1.6µA during
active video, which tilts a horizontal line by 2mV at the
Y output
