Digital Power Supply Bypassing
V
DD
and V
SS
are the digital power supply and ground pins for the MC3PHAC.
Fast signal transitions connected internally on these pins place high, short-
duration current demands on the power supply. To prevent noise problems,
take special care to provide power supply bypassing at the V
DD
and V
SS
pins.
Place the bypass capacitors as close as possible to the MC3PHAC. Use a high-
frequency-response ceramic capacitor, such as a 0.1
μ
F, paralleled with a bulk
capacitor in the range of 1
μ
F to 10
μ
F for bypassing the digital power supply.
Analog Power Supply Bypassing
V
DDA
and V
SSA
are the power supply pins for the analog portion of the clock
generator and analog-to-digital converter (ADC). On the schematics in this
document, analog ground is labeled with an A and other grounds are digital
grounds. Analog power is labeled as +5 A. It is good practice to isolate the
analog and digital +5 volt power supplies by using a small inductor or a low
value resistor less than 5 ohms in series with the digital power supply, to create
the +5 A supply. ADC V
REF
is the power supply pin used for setting the ADC’s
voltage reference.
Decoupling of these pins should be per the digital power supply bypassing,
described previously. ADC V
REF
(pin 1) and V
DDA
(pin 3) shall be connected
together and connected to the same potential as V
DD
.
