PINOUTPUT
SYMBOLPIN NAMEDESCRIPTION
No.TYPE
AM (MW and LW bands) intermediate frequency (IF) input
pin.
The input amplitude is 0.1 VP-P. Since there is an onchip AC
amplifier, block the DC component of the input signal with
a capacitor. This pin is valid when the initialize diode matrix
DISAMIF switch is 0.
This pin is used for detecting the presence of a broadcast
station during MW and LW band autotuning. The input
frequency ranges and input conditions for determining the
presence of a broadcast station are shown below.

Input frequency ranga 1 is the frequency that must be
input within 20 ms after the PLL is lockde.
Input frequency range 2 is the frequency that must be
input within 40 ms after 1 was input.
When both input frequency ranges 1 and 2 are satisfied,
a broadcast station is judged to be present and autotuning
stops.
FM band intermediate frequency (IF) input.
The input ampltude is 0.1 VP-P. Since there is an AC
amplifier on the chip, block the DC component of the input
signal with a capacitor. This pin is valid when the initialize
diode matrix switch ENFMIF is 1.
This pin is used for detecting the presence of a broadcast
station during FM band autotuning. The input frequency
ranges and input conditions for determining the presence
of a broadcast station are shown below.
