s INSTRUCTIONS AND DIRECTIONS FOR USE
(1) Standard circuit
The SAG correction circuit reduces output coupling capacitor values.
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.
