(kHz)
(V)
Composite sync pulse output; sync pulses start on a falling edge and end on a rising edge
AC coupled composite video input; sync tip must be at the lowest potential (positive picture phase)
Vertical sync pulse output; the falling edge of vert sync is the start of the vertical period
Supply ground
Low when input horizontal frequency is greater than 20kHz
(An external capacitor to ground); bypass pin for internal bias generator.
Horizontal output; falling edge active
