Function And Description

Applies voltage of VCC = 3.0 to 5.5V

Inputs local oscillation signal in FM band.

fIN = 50 to 200MHz, FMIN input signal is

output by 1 / 1 dividing (buffer amplifier).

Inputs local oscillation signal in TV band.

FIN = 50M to 1.0GHz, TVIN input signal is

output by 1 / 8, 1 / 4, or 1 / 2 dividing,

which is controlled with N1 and N2 input.

Grounds.

Outputs dividing signal.

These inputs control the selection of a

dividing ratio among 1 / 1, 1 / 2, 1 / 4, and

1 / 8.

FMIN terminal is selected at N1 = N2 = "L"

level (1 / 1 dividing).

The truth table is shown below.

Connects capacitors on bias circuit.

Change this pin into low, the IC is

turned stand-by mode.
