To determine the value for the resistor and capacitor,
the formula is:
Where R is in ohms and C is in microfarads. Some pos-
sible combinations are given below. To minimize the

These pins provide power and ground for the AUI and
twisted pair receive circuitry. No specific decoupling
has been necessary on these pins.
