2. High-level signal detection block
Sync.-in pin (pin 21) is a pin for inputting the sync.-on green signal and it is separated into the
composite sync. signal (composite sync.) inside. H-in 1 and 2 pins (pin 13 or pin 14) are input
pins for the video signal and the separated horizontal signal.
The high-level signal detection block discriminates the presence of H-in signal which is
selected in SW block and provides the output to H-out pin (pin 19) in the following manner.
H signal detection pin (pin 20) voltage becomes under 1 V or over 4 V if H. sync. signal is not
inputted.
The output signal for the H. sync. signal detection pin voltage becomes as follows and it has
hysteresis characteristics. It is possible to adjust the H. sync. signal detection time by means of an
external capacitor.
