CXA1744AR
Description of Operation
• The signals which have been input from Pins 38 and 39 are mixed with the local oscillation signal from the
oscillator and multiplier at the mixer, and the frequency-converted signal is output from Pin 37. The oscillator
can be self-oscillated by composing the Colpitts-type crystal oscillation circuit between Pins 47 and 48. Also,
the external local oscillation signal can be directly input to Pin 47.
• After the bandwidth is limited by filter, the mixer output signal is amplified by the IF amplifier and output from
Pin 31. The IF amplifier output signal is limited its bandwidth again, and the amplitude is limited by the limiter
amplifier and output from Pin 24. The limiter amplifier output signal is phase-shifted by LC resonance circuit
and the signal is output from Pin 9 after being quadrature-detected.
• The RSSI output is the currents corresponding to the input level at the IF amplifier and limiter amplifier. The
current signal can be converted into a voltage signal by connecting a proper I-V conversion circuit to Pin 21.
Notes of Operation
Take care of the followings because the CXA1744AR has the IF amplifier voltage gain of approximately 34
dB and limiter amplifier voltage gain of approximately 67 dB and uses high frequency.
1. Use as wide pattern as possible for the power supply line and GND, and insert a by-pass capacitor as
close to them as possible.
2. Separate the input line from the output line as far as possible and make the wiring short.
3. Ground the decoupling capacitors of mixer (Pins 38, 40 and 42), IF amplifier (Pins 33 and 35) and limiter
amplifier (Pins 26 and 28) as close to each pin as possible.
Notes on Application
1) Power supply
This IC has a built-in voltage regulator so that the supply voltage range is wide (2.7 to 5.5 V) and stable.
There are three power supply pins and GND pins (Pins 19, 13 and 36, 1 and 30, 25).
Ground a decoupling capacitor as close to each power supply pin as possible.
2) Oscillator
The oscillator in this IC varies its current consumption according to the oscillation level.
The figures below show how to use the CXA1744AR oscillator.
(a) Configuring a Colpitts oscillation circuit.
(b) Inputting a local oscillation signal from an external circuit.
Input a signal of approximately 0 dBm to stabilize the oscillator operation and reduce the current
consumption.

3) Multiplier
The ×5 multiplier is provided in this IC for mixer local signal. The fifth-order component of the input signal is
extracted by the resonance circuit connected to Pin 44 externally. Wire the resonance circuit as close to
Pin 44 as possible.
4) Mixer
The CXA1744AR mixer is of double balanced type. Its input is at Pins 38 and 39; when input from Pin 39,
Pin 38 should be grounded with a capacitor.
5) 10.7 MHz filter
The mixer output impedance and IF amplifier input impedance are approximately 330 Ω. The IF amplifier
output impedance and limiter amplifier input impedance are approximately 460 Ω. Use the 10.7 MHz filter
with matching.
6) Detector
For quadrature FM detection, the phase of the limiter output (Pin 24) is shifted 90° by the RLC parallel
resonance circuit or discriminator as the output is input to pin 23.
The phase shifter by RLC parallel resonance circuit is shown below. In this case, values of L and C are
determined so that the center frequency of the second IF signal and the parallel resonance frequency are
equal. As the value of R sets the detector output level, select this value so as to obtain the required output
level.
With regards to the detector input, the center frequency of the second IF signal and the frequency for the
minimum value of the detector distortion does not match because the internal delay is more than the
external one. Add the delay circuit as shown below to match the center frequency of the second IF signal
and the frequency for the minimum value of the detector distortion.

7) RSSI
RSSI detects the input signal level, and the current is output in this IC. If the voltage output is necessary, IV conversion should be made by use of a resistor, etc.
This IC can compensate for the unevenness of the filter connected between the IF amplifier and limiter
amplifier. Pin 29 is used to perform the adjustment so that the line of the RSSI output characteristics is as
straight as possible.
Also, RSSI offset adjustment pin (Pin 22) is provided in this IC. For example, the RSSI offset amount is
adjusted to match the dynamic range used in the next-stage IC.
8) Comparator
This IC has three comparators and they are designed according to the following applications.
COMP1 performs the waveform shaping of the demodulated audio signal and outputs the resulting signal
as a rectangular wave.
COMP2 is used to detect the free channel or the signal strength after the RSSI output voltage is input.
COMP3 is the current output-type comparator. The COMP3 output can be turned ON/OFF by setting Pin
32 High/Low and this comparator can form a part of a sample-and-hold circuit. The rise time of the
demodulated signal during burst operating can be shortened.
9) PSX
This is the power save control pin (Pin 2). The power save function is performed by setting this pin Low;
the functional blocks except OSC are in the power save mode.
