Power-S upply S equenc ing
The MAX2108 has several +5V supply pins. Configure
the supply layout in a star format, with a bypass capac-
itor that dominates the rise time of the supply at the
center of the star to ensure that all pins see approxi-
mately the same voltage during power-up.
Filters in Direc t-Conversion T uners
Typically, a 5th- or 7th-order L-C lowpass filter is used
for anti-aliasing the ADCs following the MAX2108.
Table 1 offers suggested component values for these
lowpass filters. Figures 1 and 2 describe typical filtering
requirements.
