Page 4: Circuit Description
CIRCUIT DESCRIPTION TUNING VOLTAGE GENERATOR VCC6 IC500 MSC1169MS-K VREF Figure 1 This circuit generates the DC tuning voltage BT for selecting a channel with a TU pulse being output from IC700. IC500 has 3 circuits for converting pulses to voltages; it selects one of VHF-L, VHF-H, or UHF, and causes the tuning voltage to be output from the OUT terminal (pin 12). - Page 5 POWER SUPPLY VCC1-1 T100 D155 CP100 VCC7 D152 CP108 VCC6 CP107 Q111 VCC2 Vref L101 C135 CP109 R115 D152 D150 D100 C140 VR100 VEE1 Q100 CP110 Q101 CP104 Figure 3 The power supply consists of a DC-DC converter and causes the voltages to be output as shown in Table 2.
