MULTIPLIER AND ZERO DELAY BUFFER
CLK/2
The ICS570 requires a 0.01µF decoupling capacitor to be connected between VDD and GND. It must be connected
close to the part to minimize lead inductance. No external power supply filtering is required for this device. A 33Ω
series terminating resistor can be used next to each output pin.
