frequency input
The nominal input level of this pin is 1 V p-p. The input range is
12 MHz to 464 MHz. This pin is internally biased and must be ac-
coupled and terminated externally with a 50 Ω resistor. Place
the ac coupling capacitor between the pin and the resistor.
When driven from an 50 Ω RF signal generator, the recommended
input level is 4 dBm.
