Pin Description
Clock Input. 3.3 V tolerant input.
Clock Output 1.
Clock Output 2.
Clock Output 3.
Clock Output 4.
Connect to ground.
Connect to 1.5 V, 1.8V, 2.5V or 3.3V.
Output Enable. Tri-states outputs when low. Connect to VDD for
normal operation.
External Components
A minimum number of external components are required for proper operation. A decoupling capacitor of 0.01 μF should be connected
between VDD on pin 7 and GND on pin 6, as close to the device as possible. A 33 Ω series terminating resistor may be used on each
clock output if the trace is longer than 1 inch.
