connector J1/DG1. On the D-Board, the level shifter IC, IC9850, changes their logic
Level from 5V to 3.3V. The output signals are applied to the Sync Processor IC, IC97
for selection between RGB sync and LVDS sync (not shown in the diagram). The
selected sync signals are output to IC9869 for analog to digital conversion. IC9869
produces the digital sync and clock signals necessary for controlling the operation o
discharge control circuit, which is also located inside IC9701. This IC produces the
Sustain control pulses, the Scan control pulses, and the Data timing pulse for the da
drive circuit boards.
