"Low" when the FM stereo signals are received.
To be pulled up to the "VDD" at 47kΩ.
"High" when signals are received. To be pulled up to the "VDD" at 47kΩ
Meanwhile, 10kΩ should be used when taking diver FIX trigger from here
and "High: 0.9VDD or more" and "Low: 250mV or less".
(Should satisfy the diver IC specifications)
"High" when noise is received. Output for the RDS. GND at 47kΩ//1,800pF.
"High" when noise is received. Output for the RDS. GND at 36kΩ//330pF.
FM stereo "R-ch" signal output or AM audio output.
Add the specified de-emphasis constant.
FM stereo "L-ch" signal output or AM audio output.
Add the specified de-emphasis constant.
EEPROM write control. Writing permissible at "Low". Normally open.
SD bandwidth signal output. For detection of detuning data for the RDS.
AM detector output. r out < 100Ω
Power supply pin for the digital section.
DC 5V +/- 0.25V. Be careful about overlapping noise in the logic section.

20 AMINI
AM audio input
The frequency response and the level are set by connecting an external CR
network with terminal AMIN as terminal AMDET. r in = 50kΩ
21 COMP O composite signal FM composite signal output. r out < 100Ω

23 LOCH
I
local high
FM local high pin. When seeking local high, apply 5V together with "LOCL".
24 FMLOCL I
FM local low
FM local low pin. When seeking local low, apply 5V to the base of the NPN
transistor with which the specified resistor is being connected to the emitter.
Keep it open in case of ordinary marketed models.
25 LOCL
I
local low
FM/AM local low pin. When seeking local low, apply 5V to the base of the
NPN transistor.Since this pin is exclusive for AM when the FMLOCL is in use,
do not drive it under FM.
26 RFGND
RF ground
Grounding for the antenna section.
27 FMANT I
FM antenna input FM antenna input. 75Ω. Surge absorber (DSP-201M-S00B) is necessary.
28 AMANT I
AM antenna input AM antenna input. High impedance.
Connect to the antenna through an L (LAU type) of 4.7µH.To cope with the
power transmission line hums, insert a series circuit consisting of an L
(a coil of about 100mH) + R (a resistor of 470 Ω to 2.2kΩ) between the GND.
