Full vertical sync range with constant amplitude (fV(min) : fV(max) = 1 : 2.5) can be made by chosing an application with adjustment of free–running frequency. Note 9. If higher vertical frequencies are reqiured, sync range can be shifted by using a smaller capacitor at VCAP (Pin24). Note10. Value of resistor at VREF (Pin23) may not be changed. Note 11. All vertical and EW adjustments are specified at nominal vertical settings, which means: a) ∆VAMP = 100% (IVAMP = 135µA b) ∆VSCOR = 0 (Pin19 Open–Circuit) c) ∆VPOS centered (Pin17 forced to GND) d) fH = 70kHz |
