c. 1 channel of 12-bit & 3 channels of 8-bit Dynamic DAC
The Dynamic DACs are used to generate a parabola waveform for geometric compensation.
DDAC application circuit:
D1616
2.5V
Balanced/Unbalanced
Parabola
8/12 bit resolution
DDAC
Geometry compensation parabola waveform:
DDAC0
can be used to compensate H size distortion:
1. PinCushion Correction (amplitude)
(PCC amplitude)
2. Trapezoid (Keystone)
3. CBOW (S-comp)
25%
25%
4. PinCushion correction (corner)
(PCC corner)
The PCC amplitude can be compensated against V size adjustment automatically.
The Trapezoid can be compensated against V center adjustment automatically.
DDAC1
is used to compensate H center distortion:
1. Pin balance (Bow)
2. Key balance (Tilt)
Note: The unused dynamic DACs can be used as static DACs.
