However, this circuit may cause to SAG deterioration, and lose synchronization by luminance fluctuation. Checking the waveform containing a lot of low frequency components like a bounce waveform (Worst condition waveform of SAG). Refer to Figure 1 and Figure 2. (2) SAG correction unused circuit To stabilize the synchronized signal, we recommend this circuit. Connect the coupling capacitor after connecting the Vout pin and Vsag pin. The recommended value is 470µF or more. Refer to Figure 3 and Figure 4.
