POWER SUPPLY DECOUPLING
There are thirty three VDD’s (VDD) and thirty six GND’s
(GND) on the 84302.
All VDD’s should be connected together as close as
possible to the device with a arge VDD plane. If the VDD’s
vary n potential by even a small amount, noise and atchup
can result. The VDD’s should be kept to within 50 mV of
each other.
All GND’s should also be connected together as close as
possible to the device with a large ground plane. If the
GND’s vary n potential by even a small amount, noise and
latchup can result. The VDD’s should be kept to within 50
mV of each other.
A 0.01-0.1uF decoupling capacitor should be connected
between VDD and GND for every eight sets of VDD/GND
placed as close as possible to the device pins, preferably
within 0.5". The value should be chosen on whether the
noise from VDD-GND is high or low frequency. A conser-
vative approach would be to use two decoupling capaci-
tors on each VDD/GND set, one 0.1uf for low frequency
and one 0.001uf for high frequency noise on the power
supply.
The PCB layout and power supply decoupling discussed
above should provide sufficient decoupling to achieve the
following when measured at the device: (1) The resultant
AC noise voltage measured across each VDD/GND set
should be less than 100 mVpp, (2) All VDD’s should be
within 50 mVpp of each other, and (3) All GND’s should be
within 50 mVpp of each other.
