NOTE E: The amplitude of oscillation wave at the point between the crystal and the series capacitor.
NOTE F: Remove the external capacitor connected to SYNC FILTER pin (pin 10), HV SEP1 = 00, SIG DET SW = 1(SYNC-1IN),
NOTE G: Remove the external capacitor connected to SYNC FILTER pin (pin 10). Connect 10 kΩ resistor between SYNC FILTER
NOTE H: Remove the external capacitor connected to SYNC FILTER pin (pin 10). Input a 0V - Vthnsxx [V] pulse of 15.7 kHz into
SIG DET IMPE=11. The delay time from SYNC1-IN input (525/60i) to SYNC FILTER wave form.
pin and GND. No input into SYNC1-IN. Measure the current (Ir) on the resistor. Imnsfil2xx = 3.3 / Ir - 10kΩ.
SYNC FILTER pin. The pulse voltage when SIG DET status changes.
