Electrical Characteristics (Cont’d): (VP = 12V, TA = +25°C unless otherwise specified) Parameter Symbol Test Conditions Min Typ Max Unit X–Ray Protection [XRAY (Pin2)] Slicing Voltage Level VXRAY 6.14 6.38 6.64 V Minimum Width of Trigger Pulse tW(XRAY) 10 – µs Input Resistance at XRAY (Pin2) RI(XRAY) VXRAY < 6.38V + VBE 500 – – k Ω VXRAY > 6.38V + VBE – 5 – k Ω Supply Voltage for Reset of X–Ray Latch VRESET(VCC) – 5.6 – V Vertical Oscillator (Oscillator Frequency in Application Without Adjustment of Free–Running Frequency fv(o)) Free–Running Frequency fV RVREF = 22kΩ, CVCAP = 100nF 40.0 42.0 43.3 Hz Vertical Frequency Catching Range fv(o) Constant Amplitude, Note 8, Note 9, Note 10 50 – 110 Hz Voltage at Reference Input for Vertical Oscillator VVREF – 3.0 – V Delay Between Trigger Pulsed and Start of Ramp at VCAP (Pin24) (Width of Vertical Blanking Pulse) td(scan) 240 300 360 µs Control Currents of Amplitude Control IVAGC ±120 ±200 ±300 µA External Capacitor at VAGC (Pin22) CVAGC – – 150 nF Differential Vertical Current Outputs Adjustment of Vertical Size [VAMP (Pin18)] Vertical Size Adjustment Range ∆VAMP IVAMP = 0, Note 11 – 60 – % (Referenced to Nominal Vertical Size) IVAMP = –135µA, Note 11 – 100 – % Input Current for Max Amplitude (100%) IVAMP –110 –120 –135 µA Input Current for Min Amplitude (60%) – 0 – µA Reference Voltage at Input Vref(VAMP) – 5.0 – V Adjustment of Vertical Shift [VPOS (Pin17)] Vertical Shift Adjustment Range ∆VPOS IVPOS = –135µA, Note 11 – –11.5 – % (Referenced to 100% Vertical Size) IVPOS = 0, Note 11 – +11.5 – % Input Current for Max Shift–Up IVPOS –110 –120 –135 µA Input Current for Max Shift–Down – 0 – µA Reference Voltage at Input Vref(VPOS) – 5.0 – V Vertical Shift is Centered of VPOS (Pin17) is Forced to GND Voff(VPOS) 0 – 0.1 V Note 8. 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 |
