N/C
No Connection. These pins may be connected to RF/
DC ground. Performance will not be affected.
4 RFOUT/4 Divide-by-4 output. DC block required.
6 Vcc (Dig)
Supply voltage for prescaler. If prescaler is not
required, this pin may be left open to conserve
approximately 100 mA of current.
19 RFOUT RF output (AC coupled).
21 Vcc (RF) Supply Voltage, +5V
29 VTUNE
Control voltage and modulation input. Modulation
bandwidth dependent on drive source impedance.
