External Components

The ICS650-11 requires a minimum number of external

components for proper operation. Decoupling capacitors of

0.01ìF should be connected between each VDD and GND

on Pins 4 and 6, and Pins 16 and 14, as close to the

ICS650-11 as possible. A series termination resistor of 33



may be used for each clock output. The 25.00 MHz crystal

must be connected as close to the chip as possible. The

crystal should be a fundamental mode (do not use third

overtone), parallel resonant. Crystal capacitors should be

connected from pins X1 to ground and X2 to ground to

optimize the initial accuracy. The value of these capacitors

is given by the following equation, where CL is the crystal

load capacitance: Crystal caps (pF) = (CL-6) x 2. So for a

crystal with 16 pF load capacitance, two 20 pF caps should

be used.
