Synchronization Signal
Sub-Screen Digital Processing Specifications
Note: 1. When the PLL divisor has the standard value, i.e., PLL7 to PLL3 = 10011.
2. Approximate values.
(The number of horizontal dots depends on the frame width adjustment, and the vertical H count depends on address correction.)
