Description
Crystal or clock connection. Connect to a fundamental parallel mode crystal, or clock.
VDD. Connect to +3.3 V or +5 V, and to VDD on pin 3.
VDD. Connect to VDD on pin 2. Decouple with pin 5.
Multiplier select pin 1. Determines output frequency per table above.
Connect to ground.
Connect to ground.
No connect. Nothing is connected internally to this pin.
PECL Output. Connect to resistor load as shown on page one.
Complementary PECL Output. Connect to resistor load as shown on page one.
Bias Resistor Input. Connect a resistor between this pin and VDD.
No connect. Nothing is connected internally to this pin.
No connect. Nothing is connected internally to this pin.
Output Enable. Tri-states both outputs when low. Internal pull-up.
Multiplier select pin 0. Determines output frequency per table above.
No Connect. Nothing is connected internally to this pin.
Cr stal connection. Connect to cr stal, or leave unconnected for clock input.
*Use this selection to get
155.52 MHz from a 16 MHz
input.
For lowest phase noise
generation of 155.52 MHz,
use a 19.44 MHz crystal and
the 8X selection.
