ML6428  
S-Video Filter and 75Line Drivers with Summed  
Composite Output  
Features  
General Description  
• 6.7MHz Y and C filters, with CV out for NTSC or PAL  
• 75cable line driver for Y, C, CV, and TV modulator  
• 43dB stopband attenuation at 27MHz  
• 1dB flatness up to 4.8MHz  
The ML6428 is a dual Y/C 4th-order Butterworth lowpass  
video filter optimized for minimum overshoot and flat group  
delay. The device also contains a summing circuit to gener-  
ate filtered composite video.  
• No external frequency select components or clocks  
• 12ns group delay flatness up to 10MHz  
• 5% overshoot on any input edge  
• AC coupled input and output (ML6428CS-1)  
• AC coupled input and DC coupled output  
(ML6428CS-2)  
TheY and C input signals from DACs are AC coupled into  
the ML6428. Both channels have DC restore circuitry to  
clamp the DC input levels during video sync. The Y channel  
uses a sync tip clamp. The CV and the C channels share a  
feedback clamp.  
• 0.4% differential gain on all channels, 0.4º differential  
phase on all channels  
• 0.7% total harmonic distortion on all channels  
• 5V ±10% operation  
All outputs must be AC coupled into their loads for the -1  
version. The -2 version is DC coupled. All inputs (-1 and -2  
versions) are AC coupled. TheY or C outputs can drive  
2VP-P into a 150load, while the CV output can drive  
2VP-P into 75. Thus the CV output is capable of driving  
two independent 150loads to 2VP-P.  
• DC restore with low tilt  
On the CV output, one of the 75loads can be shorted to  
ground with no loss of drive to the remaining load. The Y, C  
and CV channels have a gain of 2 (6dB) with 1VP-P input  
levels.
