STV2050A - CONVERGENCE
9.1.1 Position Offset (also called “static”)
This value is added to each dynamic value of the corresponding channel. It is used to reach an
optimal dynamic value range, and to make a first rough correction.
E1 Register: Horizontal
E2 Register: Vertical
The Position offset values are in two’s complement.
9.1.2 Gain Correction
This gain value is applied to the sum of the dynamic value and the position offset (see
26 "Convergence Values Computation Path" on page
the amplification spread of the external components. (Also refer to
Block Diagram" on page
The gain value is divided into 2 ranges, coarse and fine correction.
E0 Register: Coarse
D0 Register: Fine horizontal
D1 Register: Fine vertical
