MAX4397
Power Supplies and Bypassing
The MAX4397 features single 5V and 12V supply opera-
tion and requires no negative supply. The +12V supply
V12 is for the SCART switching function. For pin V12,
place all bypass capacitors as close as possible with a
10F capacitor in parallel with a 0.1F ceramic capacitor.
Connect all VAUD pins together to +5V and bypass with a
10F electrolytic capacitor in parallel with a 0.47F low-
ESR ceramic capacitor to audio ground. Bypass VAUD
pins with a 0.1F capacitor to audio ground. Bypass
AUD_BIAS to audio ground with a 10F electrolytic in
parallel with a 0.1F ceramic capacitor.
Bypass VDIG with a 0.1F ceramic capacitor to digital
ground. Bypass each VVID to video ground with a 0.1F
ceramic capacitor. Connect VVID in series with a 200nH
ferrite bead to the +5V supply.
Layout and Grounding
For optimal performance, use controlled-impedance
traces for video signal paths and place input termina-
tion resistors and output back-termination resistors
close to the MAX4397. Avoid routing video traces par-
allel to high-speed data lines.
The MAX4397 provides separate ground connections
for video, audio, and digital supplies. For best perfor-
mance, use separate ground planes for each of the
ground returns and connect all three ground planes
together at a single point. Refer to the MAX4397 evalu-
ation kit for a proven circuit board layout example.
