CXA3176N
Application Notes
1) Power Supply
The CXA3176N, with built-in regulator, is designed to permit stable operation at a wide range of supply
voltage of VCC1=1.1 to 4.0 V and VCC2=2.5 to 4.0 V. Decouple the wiring to VCC (Pins 4 and 19) as close
to the pin as possible.
2) Oscillator Input
Oscillator input method
a) Using Pins 1 and 2, input a self-excited oscillation signal through the composition of a Colpitts type
crystal oscillator circuit.
b) Directly input a local oscillation signal to Pin 1.
3) Mixer
The mixer is of double-balance type. Pin 24 is the input pin. Input though a suitable matching circuit. The
input impedance is 2.0 kΩ.
Pin 3 serves as the output pin for the mixer, and a load resistance of 1.5 kΩ is incorporated.
4) IF Filter
The filter to be connected between this mixer output and the IF limiter amplifier input should have the
following specifications.
I/O impedance : 1.5 kΩ ±10 %
Band width : Changes according to applications.
5) IF Limiter Amplifier
The gain of this IF limiter amplifier is approximately 100 dB. Take notice of the following points in making
connection to the IF limiter amplifier input pin (Pin 5).
a) Wiring to the IF limiter amplifier input (Pin 5) should be as short as possible.
b) As the IF limiter amplifier output appears at QUAD (Pin 8), wiring to the ceramic discriminator
connected to QUAD should be as short as possible to reduce the interference with the mixer output and
IF limiter amplifier input.

CXA3176N
6) Quick Charge
In order to hasten the rise time of Pin 7 from when power is turned on, the CXA3176N features a quick
charge circuit. The capacitance value connected to Pin 7 should be chosen such that the voltage does not
vary much due to discharge during battery saving.
Connect a signal for controlling the quick charge circuit to Pin 18. Setting this pin high enables the quick
charge mode, and setting this pin low enables the steady-state reception mode. Quick charge is used
when the power supply is turned on. The battery saving must be set high at the time.
Connect Pin 18 to GND when quick charge is not being used.
7) Detector
The detector is of quadrature type. To perform phase shift, connect a ceramic discriminator to Pin 8.
The phase shifting capacitor for the quadrature detector is incorporated. The FM signal demodulated with
the detector will be output to AMP_OUT (Pin 14) through the internal LPF.
The CDBC450CX50 (MURATA MFG. CO., LTD.) ceramic discriminator is recommended for the
CXA3176N.

8) REG CONT
Controls the base bias of the external transistors.
9) LVA OUT
This pin goes high (open) when the supply voltage becomes lower. Since the output is an open collector, it
can be used to directly drive the CMOS device. The setting voltage of the LVA is 1.05 V (typ.), and it
possesses a hysteresis with respect to the supply voltage. The hysteresis width is 50 mV (typ.).
10) B.S.
Operation of the CXA3176N can be halted by setting this pin low. This pin can be connected directly to the
CMOS device. The current consumption for battery saving is 10 µA or less (at 1.4 V).
11) Control Pins
The function controls are as shown below.
Note) When each function is not controlled externally, set it to the state with an asterisk (∗).
12) LPF Constant
The composition of the data filter is ternary.
The first-stage cut-off fC1 is

13) AFC
The AFC is of the current output type which outputs the frequency deviation in the form of the current and
converts it to the voltage. The output current range is approximately ±0.4 µA for the slow mode and ±70
µA for the fast mode.
CXA3176N AFC Principle Diagram
The Pin 7 voltage V continues to change till the Vin value reaches the Vref value. When these values are
equal, the Pin 7 output current becomes “0” and the voltage is determined by the charge and time.
The Pin 7 voltage V is output to Pin 6 through the amplifier.
Vout=Vref+4 (V–Vref)
The Vout operating range is 0.4 V to 4 (VCC–0.2) V so that AFC should be set within this range.
Also, the voltage for Pin 7 is undefined with the IC itself.
The AFC voltage varies, for example, as shown below by the VCO characteristics. The AFC voltage
follows the VCO characteristics because this voltage is independent of the slope of the S curve. In other
words, the CXA3176N operates according to the VCO characteristics when the VCO characteristics have
the linearity with respect to the voltage and the VCO characteristics can be controlled within the range
shown in the graph below.

14) Sensitivity Adjustment Method
The constants shown in the Application Circuit are for the standard external parts. However, adjustment
may be necessary depending on the conditions of use, characteristics of external parts, and the RF system
circuit and decoder connected to the IF IC, etc. Adjust the sensitivity according to the following
procedures.
a) MIX IN matching
When using a matching circuit between the RF system circuit and MIX IN of the CXA3176N, adjust the
trimmer to obtain the optimal sensitivity while monitoring the AUDIO output.
b) Local input level
The mixer circuit gain is dependent on the local signal input level to OSC IN. The input level to OSC IN
should be set as high as possible within the range of –6 to +2 dBm as shown in the graph of “Local input
level vs. Mixer gain characteristics”. However, care should be taken as raising the input level above +2
dBm will cause the sensitivity to drop.
When creating the local signal using the internal oscillator circuit, the oscillation level varies according to
the external capacitances attached to Pins 1 and 2 and the characteristics of the used crystal. Therefore,
be sure to adjust the external capacitance values attached to Pins 1 and 2 according to the crystal
characteristics.
C1 and C2 have the following range in the figure above.
C1 ≥ C2
C1 = C2 to C1 =5C2
As for the ratio of C1 to C2, the oscillation stabilizes as C1 approaches equality with C2.
The oscillation level decreases as the C1 and C2 values become larger, and increases as the C1 and C2
values become smaller.
Use a FET probe to confirm the local input level.
c) LPF constant (when the CXA3176N is used for the pager)
The data filter cut-off may need to be changed depending on the characteristics of the connected decoder.
Adjust the capacitance values of Pins 9 to 12 while checking the incoming sensitivity including the decoder.
If the capacitance values are too large, the detector output waveform will deviate at high data rates,
causing the sensitivity to drop. Conversely, if the capacitance values are too small, the LPF will be easily
affected by noise, causing the sensitivity to drop.
Adjust capacitance values of Pins 9 to 12 so that the capacitance value described in “12) LPF Constant”
becomes smaller.

CXA3176N
d) AFC
The CXA3176N uses the AFC to correct the IF frequency deviation. WHen the IF frequency deviation
amount is large, correction takes time and may lower the sensitivity. Adjust the oscillator frequency of the
local oscillator so that the center frequency of the signal input to Pin 5 (IF IN) is as close to 450 kHz as
possible.
15) CXA3176N Standard Board Description
• Outline
This board contains the external parts shown in the Application Circuit in order to evaluate the
CXA3176N operation
• Features
The following CXA3176N basic operations can be checked.
1) Battery saving and other mode switching
2) AFC pin
3) The RSSI pin output is the low impedance because it is output via the buffer.
• Method of use
1) Input the CXA3176N supply voltage VCC1=1.4 V and VCC2=3 V.
This IC operates with a single power supply.
2) The CXA3176N uses a 21.245 MHz crystal. Input the RF signal from the RF pin and use this IC in
the condition where IF=450 kHz.
3) The AFC pin voltage is undefined with the IC itself because the current output circuit is employed for
the AFC. For the evaluation, be sure to apply the bias externally to the AFC pin or to make the AFC
loop.
4) Set the mode switches.
• Mode switch setting
Mode switches S1 and S2 are provided in two locations in the board. Each basic operation can be
confirmed by switching these mode switches while referring to the board layout. See the table in “11)
Control Pins” for the mode switching.
• Device specification
