The > mark found on some component parts indicates
the importance of the safety factor of the part.
Therefore, when replacing, be sure to use parts of
identical designation.
Symbol indicates a resistor.
No differentiation is made between chip resistors and
discrete resistors.
NOTE :
Symbol indicates a capacitor.
No differentiation is made between chip capacitors and

The diagnostic result of each model is displayed.
Results are [OK], [NCON],[CHEK], and [EXCH].
OK : No error code
NCON : EMV has judged it as the thing without connection.
(Disconnection being possible if there is actually connection)
CHEK : An error code indicating that diagnosis is judged to be necessary is entered.
EXCH : An error code indicating that exchange is judged to be necessary is entered.

1 STIND O stereo "Low" when the FM stereo signals are received.
indicator To be pulled up to the "VDD" at 47kΩ.
2 FMSD FM station "High" when signals are received. To be pulled up to the "VDD" at 47kΩ
detector 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)
3 NL1 O noise level-1 "High" when noise is received. Output for the RDS. GND at 47kΩ//1,800pF.
4 NL2 O noise level-2 "High" when noise is received. Output for the RDS. GND at 36kΩ//330pF.
5 Rch O R channel FM stereo "R-ch" signal output or AM audio output.
output Add the specified de-emphasis constant.
6 Lch O L channel FM stereo "L-ch" signal output or AM audio output.
output Add the specified de-emphasis constant.
7 WC write control EEPROM write control. Writing permissible at "Low". Normally open.
8 SDBW O SD bandwidth SD bandwidth signal output. For detection of detuning data for the RDS.
9 AMDET O AM detector AM detector output. r out < 100Ω

14 DI/DO I/O data input/ Data input/Data output
data output To be pulled up to the "VDD" at 47kΩ
15 CK I clock Clock input To be pulled up to the "VDD" at 47kΩ
16 CE1 I chip enable-1 AF·RF chip enable. Active at "High"To be grounded at 47kΩ
17 AMPNS AM PNS IF signal IF signal output for AM PNS circuit.
18 LDET O lock detector Active at "Low". To be pulled up to the "VDD" at 47kΩ
19 CREQ I current request Active at "Low". To be grounded at 47kΩ
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
22 VCC power supply Analog section power supply pin.DC 8.4V +/- 0.3V
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.
