Note E: This is the amplitude of the oscillation wave at the point between the crystal and the series capacitor.
Note F: Remove the external capacitor connected with the SYNC FILTER pin (pin 14), HV SEP1 = 00, SIG DET IMPE = 11. The
delay time from SYNC1-IN input (525/60i) to the SYNC FILTER waveform.
Note G: Remove the external capacitor connected with the SYNC FILTER pin (pin 14). Connect 10 k
resistor between the SYNC
FILTER pin and GND. No input into SYNC1-IN. Measure the current (Ir) on the resistor. Imnsfil2xx = 3.3 / Ir – 10 k
.
Note H: Remove the external capacitor connected with the SYNC FILTER pin (pin 14). Input a 0 V - Vthnsxx [V] pulse of 15.7 kHz
into the SYNC FILTER pin. The pulse voltage during SIG DET status changes.
