The Convergence/Deflection Board is located on the bottom side
of the card cage under the Horizontal/Vertical Deflection Board.
This board drives the convergence coils of the projectors.
The following functions are provided by C/D Board:
• Generation of various waveforms for the horizontal and vertical
axes
• Height control
• Generation of waveforms for dynamic focus
• Various geometry correction functions for the horizontal and
vertical axes
• Convergence output amplifiers for all colors and both
horizontal and vertical axes
• Convergence enable and raster fill function
• ILA
®
assembly driver circuitry with temperature compensation
• Phase locked loop for ILA ®
assembly drivers
• IIC serial bus interface
The Convergence/Deflection Input/Output diagram (Figure 2-15)
and the list of inputs and outputs (Tables 2-12 and 2-13) provide
information for the technician to perform module level
