Sync Signal Process
Figure 11
On the DG-Board, the sync signals retrieved from the input device enter the sync
switch (IC8071). The selected sync signals are output to the D-Board via pins 31,
32, and 34 of connector DG3/D3. The sync signals then enter a level shifter IC,
IC9023, to change the DC Level from 5 to 3.3 volts. The output signals of IC9023
enter IC9009 for conversion into digital pulses. IC9605, the Sync Processor and
Discharge Control circuit, produces the Sustain control pulses, the Scan control
pulses, and the data timing pulse for the data drive circuit boards.
