Functions
1. Waveform Shaper Circuit (comparator)
The output data (pin 30) are inverted.
2. RSSI Function
DC potential corresponding to the input level of IF IN (pin 8) is output to RSSI (pin 23). Output to
RSSI (pin 23) is converted to a voltage by the internal resistance. Thus, connecting external resistance R
to pin 21 varies the gradient of the RSSI output as shown below. Note that due to the displacement of
temperature coefficients between external resistor R and the internal IC resistor IC resistor, the
temperature characteristic of the RSSI output may change. Also, the maximum RSSI value should be
V
CC
- 0.8 V or less.
Figure 1
Figure 2
3. S Curve Characteristics
Changing external capacitance C27 varies the gradient of the S curve characteristics as shown below.
In case of widening the detection range, heightening IF frequency or lowering demodulation output,
make the gradient of the S curve characteristics gentle less than typical (120pF).
When using this IC by about 2.2V (low supply), set the constant of C27 100pF or add attenuator to AF
OUT (24 pin).

11. Treatment of FM Terminal when Using AM
When using AM, it is not necessary to treat the QUAD pin (pin 11). Leave it open or connected to an
FM external circuit. To use the bit rate filter, connect the RSSI pin (pin 23) to the bit rate filter through a
resistor. The AF-OUT pin (pin 24) should be left open.

12. Control Terminal for Quick Charge Circuit (CHARGE)
CHARGE (18 pin) is control terminal for quick charge circuit. REF (22 pin) control terminal for quick
charge a given period by time constant of internal resistance and outside capacitance. Enabling the
CHARGE pin requires an external capacitor. In normal operation, connect a capacitor having the same
capacitance as that of the capacitor connected to the REF pin (pin 22).
If the connected external capacitor (C30) is 0.1
F, the quick charge time is 7 ms (typically).
13. Bit Rate Filter for FM
The current FM bit rate filter is used as a tertiary filter.
If the filter is to be used at a rate other than 1200 bps, please change the filter constant.

For the cutoff frequency of the bit rate filter, specify a sufficiently high value for the bit rate to be used.
Specifying a relatively high cutoff frequency for the bit rate filter enables a low capacitor to be used at
the REF pin, therefore making the pulse rise quickly.
When AM is used, the internal resistance of RSSI is used. So, take the output resistance into account
when specifying a cutoff frequency.

Cautions for Designing Circuit Board Patterns
Observe the following cautions when designing circuit patterns for this product.
Local Oscillator Circuit (pin 1)
Isolate the local oscillator circuit block sufficiently from the RF amp block.
Isolate the local oscillator circuit block securely so that its output will not get in the IF input, IF filter, or
mixer input.
Do not place the local oscillator circuit block too close to the ceramic filter.
Subdivide the ground pattern for the local oscillator circuit block, and connect the subdivisions with thin
lines.
IF Input and Output Block (pin 8, 10)
Isolate the input from output patterns of the IF filter and detector block securely from each other.
Demodulator Circuit Block (pin 11)
Isolate the demodulator circuit block sufficiently from the IF input block (pin 8).
Do not place the LC too close to the IC device.
Data Output Block (pin 30)
Isolate the data output block sufficiently from the IF input block (pin 8).
Isolate the output pattern of the data output block from other circuits as much as possible, so any noise from
a stage subsequent to the output will not affect them.
RF Amp Circuit Block
1)
Preventing RF amp oscillation
Do not place the patterns connected to pins 16 and 17 too close to each other.
Isolate the patterns connected to the input block (pin 16) and output block (pin 19) from each other.
Make the RF input signal line relatively thin.
Place a relatively wide ground pattern between the RF-IN pin (pin 16) and RF-DEC pin (pin 17).
Connect the RF-OUT pin (pin 19) and MIX-IN pin (pin 20) with the shortest possible pattern.
2)
Attaining a sufficient gain
To attain a sufficient RF amp gain, select an optimum value for the input matching circuit block (pin 16)
according to the board circuit pattern.
3)
Sharing antenna with receiver and transmitter
Using hi power application, place the patterns connected to SAW filter and pin 15 close.
IC Mounting Area
Provide a ground pattern under the IC device, and prepare relatively many through holes.
Cautions for mounting
Mount better accurate constants of capacitance in IF filter block and detector block.
