Description
RF Ground. Tie all ground pins together.
Single-Ended 50 Ω Input to the RF Prescaler. This pin is ac-coupled internally via a 3 pF capacitor.
No Connect. Do not connect to this pin.
Chip Enable. This pin is active high. When CE is brought low, the part enters power-down mode. If this
functionality is not required, the pin can be left unconnected because it is pulled up internally through
a weak pull-up resistor.
Divided-Down Output of the Prescaler. This pin has an internal 100 Ω load resistor tied to VDD2 and an
ac coupling capacitor of 1 pF.
Complementary Divided Down Output of the Prescaler. This pin has an internal 100 Ω load resistor tied
to VDD2 and an ac coupling capacitor of 1 pF.
Voltage Supply for the Output Stage. Decouple this pin to ground with a 0.1 µF capacitor in parallel with a
10 pF capacitor. VDD2 can be tied directly to VDD1.
Voltage Supply for the Input Stage and Divider Block. Decouple this pin to ground with a 0.1 µF capacitor
in parallel with a 10 pF capacitor.
The LFCSP has an exposed paddle that must be connected to GND.
