AN2514S ICs for Video Camera Pl @ Supplementary Explanation + Precautions on Use 1, Horizontal free oscillation frequency adjusting method ‘The frequency of Pin should essentially be adjusted to 15.75Hz by the counter, changing the resistor of Pin{ at no signal input. But this causes the voltage of Pin (AFC detecting pin) to be about 2V when a signal is input. Because supply voltage is 5V (typ.), it is desirable to use a digital voltmeter so that the voltage of Pind) may be 2.5V, considering dispersion, etc. 2. External constant of Pin ‘The following value is recommeded to take in the dispersion of horizontal free oscillation frequency of IC. S 100K “ares 2 3. Vertical oscillating R.C High-precision parts should be used for the grounding resistor of Pin® and grounding capacitor of Pin@) which determine vertical free-oscillation frequency. Because of 54Hz (typ.) at C;=0.1 F and Re=30k 2, the value of Re is desirable to be 33 to 36k 0, considering the dispersion and temperature characteristics of IC in ordemnot to be out of vertical synchronization, 4, Power filter It is recommended to use the following filter for power pins of Pins@) and @, to prevent from being out of vertical synchronization and horizontal noise. C2 of good temperature characteristics should be used.
