Keep in mind that inside the SICOFI-2/4 TE all the different
Semiconductor Group
a) Separate all digital supply lines from analog supply lines as much as possible.
b) Use a separate GND-connection for the capacitor which is filtering the reference
c) Don’t use a common ground-plane under the SICOFI-2/4-TE.
d) Use a large ground-plane (distant from the SICOFI-2/4-TE) and use three single
a) To achieve a good filtering for the high frequency band, place SMD
b) One 100 nF SMD ceramic-capacitor is needed to filter the digital supply
c) Place all filter capacitors as close as possible to the SICOFI-2/4-TE
d) Use one central Tantalum-capacitor with about 1 F to 10 F to block
voltage (220 nF ceramic-capacitor at
ground lines for connecting the SICOFI-2/4-TE: one common analog ground, one
digital ground, and a third for the 220 nF capacitor connected to
ceramic-capacitors with 100 nF from
