NJM2561A - 4 - 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 470f or more. refer to figure 3 and figure 4. figure 1 figure 2 c1: 100f, c2: 22f c1: 100f, c2: 22f input signal: 1vp-p, white black waveform input signal: 1vp-p, black white waveform orange: vout pin waveform orange: vout pin waveform green: waveform after output capacitor green: waveform after output capacitor figure 3 figure 4 output coupling capacitor: 470f output coupling capacitor: 470f input signal: 1vp-p, white black waveform input signal: 1vp-p, black white waveform orange: vout pin waveform orange: vout pin waveform green: waveform after output capacitor green: waveform after output capacitor
