CLAMP/BIAS
APPLICATION CIRCUIT
This circuit drives two-line of 150Ω. However, it may cause to lose synchronization by an input signal of large APL change
(100% white signals more than 1Vp-p). Confirm the large APL change waveform (100% white signals more than 1Vp-p) and
evaluate sufficiently.
CLAMP/BIAS
This circuit is for a portable equipment of small mounting space.
The SAG correction reduces output coupling capacitor values.
However, this circuit may cause to SAG deterioration, and lose synchronization by luminance fluctuation.
Adjust the C1 value, checking the waveform containing a lot of low frequency components like a bounce waveform (Worst
condition waveform of SAG). Change the capacitor of C1 into a large value to improve SAG.
We recommend this circuit when there is no space limitation.
Connect the coupling capacitor after connecting the Vout pin and Vsag pin. The recommended value is 470µF or more.
