Pin 5 supplies sync input from outside to Pin 5 through embedded interface and at this time,
according to capacitor value of C305 connected to Pin 5, pulse width is determined.
Pin 6 outputs horizontal output pulse and its range is from 27Khz to 70Khz.
Pin 7.20 is used as terminal supplying B+ of device.
Pin 8 receives feedback for pulse from No. 6 terminal of FBT, compares and detects it so
that it operates in sequence of detected feedback to maintain high-voltage constantly.
Pin 9 determines gradient of waveform in oscillation cycle of oscillator and is determined by
C306 capacitor value.
Pin 10 controls H-phase by adding or subtracting it with DC voltage and its circuit is
composed of C308, R310, R309 and VR305.
Pin 11 is used as GND of IC301.
Pin 12 and Pin 18, terminal controlling vertical frequency, is controlled with DC level and its
circuit is composed of R318, C311, R317, R316, VR301 and R332.
Pin 14 is used as input terminal of vertical SYNC and always receives negative signal.
Pin 15 is used as vertical output terminal.
Pin 16 is a terminal used to control the vertical size and its vertical size varies with DC level
input to Pin 16 and is composed of C315, R307, R308 and VR304.
Pin 17 controls vertical linearity according to DC level input to Pin 17 and is composed of
R305, C313, C302, R306 and VR303.
Pin 19 is a terminal used to supply the reference voltage.
