The objective of the dynamic DAC is to generate geometric compensation parabola waveforms.
Several examples are given below.
L-3. Examples
L-3.1 DDAC0 used to compensate for H size distortion
1. Pincushion (PCC amplitude)
2. Trapezoid (Keystone)
3. CBOW (S-comp)
25%
25%
4. PCC corner
L-3.2 DDAC1 used to compensate for H center distortion
1. Pin balance (Bow)
2. Key balance (Tilt)
M. Sync Processor
The sync processor is composed of a polarity detector, sync separator, H/V frequency counter, H/V
dummy frequency generator, H-clamp generator, and SOA generator. Figure 11 is a block diagram of
the sync processor. The related control bits are defined in SFR CONTREG2. The sync processor
supports powerful functions that enable users to employ the V/H , H-clamp, and SOA outputs to easily
control and protect the deflection circuit.
