Place the 1nF power-supply decoupling capacitors
between the star connection and the smaller bypass
capacitors and close to the IC. Larger trace lengths
between the decoupling capacitors and the IC increase
the parasitic trace inductance, which, when combined
with the capacitors on V
CC1
and V
CC2
, can form an LC
tank and introduce instability in the MHz range. If this
happens, you can add a small-value resistor (~10
),
between the 1nF capacitor and ground to de-Q the
capacitor and dampen the oscillation.
