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.
