Application Circuit

r
any problems arising out of the use of these circuits or for any infringement of third party patent and other right due to same
.
--10--
CXA1999N
Application Note
1) Power Supply
The CXA1999N, with built-in regulator, is designed to permit stable operation at wide range of supply
voltage from 1.1 to 4.0 V. Decouple the wiring to V
CC
(Pin 4) as close to the pin as possible.
2) Oscillator Input
Oscillator input method
a) Using Pins 1 and 2, input 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 20 is the input pin. Input though a suitable matching circuit. The
input impedance is 2.0 k
.
Pin 3 serves as the output pin for the mixer, and a load resistance of 1.5 k
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 k
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) Be sure to wire to the IF limiter amplifier input (Pin 5) is as short as possible.
b) As the IF limiter amplifier output appears at QUAD (Pin 8), be sure to wire to the ceramic discriminator
connected to QUAD is as short as possible and reduce the interference with the mixer output and IF
limiter amplifier input.

CXA1999N
6) Quick Charge
In order to hasten the rising time from when power is turned on, the CXA1999N features a quick charge
circuit. Therefore, the quick charge circuit eliminates the need to insert a capacitor between the detector
output and the LPF as is the case with conventional ICs, but connects a capacitor to Pin 7 to determine the
average signal level during steady-state reception. The capacitance of the capacitor 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 14. 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 14 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 demodulated FM (FSK) signal
with the detector will be output to DET OUT (Pin 9) through the internal primary LPF.
DET OUT output impedance is 200
or less. The DET OUT output is the anti-phase output to NRZ OUT.
The CDBM455C28 (MURATA MFG. CO., LTD.) ceramic discriminator is recommended for the CXA1999N.

CXA1999N
8) Filter Buffer, Level Comparator and NRZ Comparator
An operational amplifier for LPF is built in this IC.
It is connected internally to the NRZ comparator, level comparator and quick charge circuit.
Using the operational amplifier of Pins 11 and 12 to construct an LPF, remove noise from the demodulated
signal and input the signal to the above three circuits.
The level comparator and the NRZ comparator shape waveform of this input signal and output it as a
square wave. The comparator output stage is for open collector.
Thus, if the CPU is of CMOS type and the supply voltage is different, a direct interface as illustrated in the
figure below can be implemented.
9) REG CONT
Controls the base bias of the external transistors.
10) LVA OUT
This pin goes high (open) when the supply voltage becomes low. Since the output is an open collector, it
can be used to directly drive 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.).
11) B.S.
Operation of the CXA1999N can be halted by setting this pin low. This pin can be connected directly to
CMOS device. The current consumption for battery saving is 20 A or less (at 1.4 V).

12) M-ary (M = 2- or 4-level) FSK Demodulation System
Polarity discrimination output and MSB comparator output are used to demodulate the 4-level waveform
shown below.
[4-level FSK demodulating waveform]
[NRZ OUT] Polarity discrimination output
(When the input frequency is higher than the local frequency)
[L.C. OUT] MSB comparator output
The 4-level FSK demodulating data is divided into an NRZ OUT and L.C. OUT shown above. Here, the
NRZ OUT corresponds to a conventional NRZ comparator output. The L.C. OUT is made comparing the
demodulated waveform amplitude to the IC internal reference voltage levels. When the threshold value of
L.C. OUT is not appropriate to the detector output, the resistance value on Pin 8 should be adjusted for
the detector output level adjustment.
For the 2-level FSK demodulation, it corresponds to a conventional NRZ comparator output.

13) Principle of Quick Charge Operation
BUF in Fig. 8 is the detector buffer amplifier, and AMP is an operational amplifier to construct an LPF.
COMP is the level comparator or the NRZ comparator. The CXA1999N has a feedback loop from the
comparator input to the input circuit of the detector output buffer. This equalizes the average value of the
comparator input voltage to the reference voltage, with the quick charge circuit of CHG being set in the
feedback loop. Switching the current of the quick charge circuit enables reduction of the rise time.
In this block, CHG is a comparator which compares input voltages and outputs a current based on this
comparison. The current on CHG is switched between high and low at Pin 14. When the power is turned
on, switch the current to high to increase the charge current at C in Fig. 8 and shorten the time constant.
During steady-state reception mode, switch the current to low, lengthening the charge time constant and
allowing for stable data retrieval.

Note on operation : Measures for the prevention of electrostatic breakdown should be taken to handle this IC.
14) S Curve Characteristics
Even if the IF IN input signal frequency is deviated, the feedback is applied to the DET OUT operating
point so as to match it to the comparator reference voltage by the quick charge operation shown in Fig. 8.
Therefore, this feedback must be halted in order to evaluate the S curve characteristics.
To execute the evaluation, measure the average voltage on Pin 12 first and input this voltage to Pin 7 from
the external power supply.
