Interface Schematic

1-3, 5, 8-11,

13-18, 20,

22-28, 30-32

N/C

No Connection. These pins may be connected to RF/

DC ground. Performance will not be affected.

4RFOUT/4

Divide-by-4 output.

DC block required

6Vcc (Dig)

Supply voltage for prescaler. If prescaler is not

required, this pin may be left open to conserve

approximately 65 mA of current.

7Vcc (Amp)

Supply voltage, for RFOUT/2 output. If RFOUT/2

is not required. This pin may be left open to

conserve approximately 30 mA of current.

12

RFOUT/2

Half frequency output (AC coupled).

19

RF OUT

RF output (AC coupled).

21

Vcc (RF)

Supply Voltage, +5V

29

VTUNE

Control voltage and modulation input. Modulation

bandwidth dependent on drive source impedance. See

“Determining the FM Bandwidth of a Wideband Varac-

tor Tuned VCO” application note.

GND

Package bottom has an exposed metal paddle that

must be connected to RF/DC ground.
