capacitor as below.
When a connected crystal oscillator is used for the XO, the following oscillation specifications are required.
Instead of connecting a crystal oscillator, it is possible to input an external CW (Continual Wave) into pin 28 through a
The required specs on the CW are as follows.
Oscillation frequency (fundamental): 3.579545 MHz (for NTSC decoding)
Frequency tolerance: +/- 50 ppm
Input frequency (fundamental): 3.579545 MHz +/- 50 ppm
Input amplitude: 1.0Vp-p +/- 0.5Vp-p
