Special care is also given to decoupling the MAX1276
power supplies. The capacitors are located as close as
possible to the MAX1276 with their ground nodes con-
nected to the analog ground plane (see
traces are as wide as possible to reduce para-
sitic inductance.
The EV kit includes three capacitor locations to support
a wide array of decoupling capacitor choices. Three
values of capacitors (10µF, 0.1µF, and 0.01µF) are

used for solid decoupling over a range of clock fre-
quencies. In most applications, a single large-value
capacitor, used in parallel with a smaller high-frequen-
cy bypass capacitor, is sufficient. The high-frequency
bypass capacitor should always be placed as close as
possible to the MAX1276 to minimize ESL/ESR effects.
Reference capacitors should be afforded the same
attention as supply decoupling capacitors. The capaci-
tors are located as close as possible to the MAX1276
