DESCRIPTION
OUTPUT
TYPE
AM (MW and LW bands) intermediate frequency (IF)
input pin.
The input amplitude is 0.1 VP-P. Since there is an on-
chip 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 broad-
cast station during MW and LW band autotuning. The
input frequency ranges and input conditions for deter-
mining the presence of a broadcast station are shown
below.

Input frequency range is the frequency that must be
input within 20 ms after the PLL is locked.
Input frequency range is the frequency that must be
input within 40 ms after was input.
When both input frequency ranges and are sat-
isfied, a broadcast station is judged to be present and
autotuning stops.
FM band intermediate frequency (IF) input.
The input amplitude 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 broad-
cast station during FM band autotuning. The input
frequency ranges and input conditions for determin-
ing the presence of a broadcast station are shown
below.
