Pin Assignment
ICS671-01
External Components
The ICS671-01 requires a minimum number of external components for proper operation. Decoupling
capacitors of 0.01μF should be connected between VDD and GND on pins 4 and 5, and VDD and GND
on pins 13 and 12, as close to the device as possible. A series termination resistor of 33
may be used close
to each clock output pin to reduce reflections.
