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.
