Description

1, 3, 4, 5, 8, 9,

12, 13, 16

GND

RF Ground. All ground pins should be tied together.

2

RFIN

Single-Ended 50 Ω Input to the RF Prescaler. This pin is ac-coupled internally via a 3 pF capacitor.

6

NC

No Connect. This pin can be left unconnected.

7

CE

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.

10

RFOUT

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.

11

RFOUT

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.

14

VDD2

Voltage Supply for the Output Stage. This pin should be decoupled to ground with a 0.1 μF capacitor in

parallel with a 10 pF capacitor and can be tied directly to VDD1.

15

VDD1

Voltage Supply for the Input Stage and Divider Block. This pin should be decoupled to ground with a

0.1 μF capacitor in parallel with a 10 pF capacitor.

EPAD

The LFCSP has an exposed paddle that must be connected to GND.
