Note: 11 These parameters are not tested on each unit. They are measured during our internal qualification procedure.
Note:
Note:
12 Set Register 07 at Byte 0xxxxxxx (S correction inhibited) and Register 08 at Byte 0xxxxxxx (C correction
inhibited), to obtain a vertical sawtooth with linear shape.
13 This is the frequency range for which the vertical oscillator will automatically synchronize, using a single
capacitor value on Pin22 and Pin 20, and with a constant ramp amplitude.
Note: 14 When not used, the DC breathing control pin must be connected to 12V.
