Switcher Delay minus the input time location within the autotiming
window (the time location value can be zero, positive, or negative).
A timing diagram of the input autotiming window and various switcher
delay values is provided in
Figure 53 .
Figure 53. Switcher Timing Diagram
• For inputs entering the switcher in zero time with the reference, the
total delay through the switcher is the Nominal Switcher Delay (A μs).
• Inputs that reach the switcher at the latest point in the autotiming
window (+B μs) will have a total delay that equals the time required for
switcher processing. This value is the Minimum Switcher Delay (C μs).
• Inputs that reach the switcher at the earliest point in the autotiming
window (-B μs) will have a total delay equal to the Nominal Switcher
Delay (A μs) plus the autotiming window range. This value is the
Maximum Switcher Delay value (D μs).
