... SCART and EVC cables are supported for composite, component, and RGB video. 1V input signals from DACs are AC coupled into the P-P ML6427 where they are DC restored. Outputs are AC coupled and drive 2V into a 150W load. The ML6427 P-P can provide DC coupled outputs for certain applications. ...

... A/Y2 or the CV INF SWAP CVF and SWAP CVU will pull low if they are not driven. The ML6427 is robust and stable under all stated load and input conditions. Bypassing both V CC ground ensures this performance. Two ML6427s can be connected in a master-slave sync configuration. When using this configuration (See Figure 6) only the “ ...

... TYPICAL APPLICATIONS USING THE ML6427 FOR PAL APPLICATIONS The ML6427 can be optimized for PAL video by adding frequency peaking to the composite and S-video outputs. Figure 10 illustrates the use of an additional external capacitor (330pF) in parallel with the output source termination resistor. This raises the frequency response from 1 ...
