Notes : 1. These parameters are not tested on each unit. They are measured during our internal qualification procedure which includes
characterization on batches comming from corners of our processes and also temperature characterization.
2. When 2V are applied on Pin 28 (Vertical S-Correction control), then the S-Correction is inhibited, consequently the sawtooth have
a linear shape.
3. It is the frequency range for which the VERTICAL OSCILLATOR will automatically synchronize, using a single capacitor value on
Pin 27 and with a constant ramp amplitude.
4. Typically 3.5V for Vertical reference voltage typical value (8V).
