1. Control Terminal for Quick Charge Circuit (CHARGE) CHARGE (15 pin) is control terminal for quick charge circuit. REF (20 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 20). If the connected external capacitor (C11) is 0.1 µF, 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.

Bit Rate Filter for AM The current AM bit rate filter is used as a quadratic filter. If the filter is to be used at a rate other than 1200 bps, please change the filter constant. Quadratic Filter (NRZ) (the bit rate filter time constant takes into account the internal resistance RSSI (30 kΩ)) R R10 C20 C19 1200 bps 36 k Ω 68 k Ω 4700 pF 1500 pF 2400 bps 36 k Ω 68 k Ω 2200 pF 680 pF 4800 bps 36 k Ω 68 k Ω 1000 pF 390 pF When the filter constants shown below are used, it is not necessary to set the R constant value.

If the filter is to be used at a rate other than 1200 bps, please change the filter constant.

Quadratic Filter (NRZ) (the bit rate filter time constant takes into account the internal resistance RSSI (30 kΩ)) R R9 R10 C20 C19 C18 1200 bps 36 k Ω 68 k Ω 68 k Ω 0.01 µF 560 pF 3300 pF 2400 bps 36 k Ω 68 k Ω 68 k Ω 4700 pF 270 pF 1500 pF 4800 bps 36 k Ω 68 k Ω 68 k Ω 2200 pF 150 pF 680 pF When the filter constants shown below are used, it is not necessary to set the R constant value. R R9 R10 C20 C19 C18 1200 bps  30 kΩ 30 k Ω 0.033 µF 2200 pF 8200 pF 2400 bps  30 kΩ 30 k Ω 0.015 µF 1000 pF 3900 pF 4800 bps  30 kΩ 30 k Ω 6800 pF 470 pF 1800 pF 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. Mixer Output Block (pin 4) to IF Input Block (pin 6) Isolate the input and output patterns of the IF filter securely from each other. Demodulator Circuit Block (pin 10) Isolate the demodulator circuit block sufficiently from the IF input block (pin 6). Do not place the LC too close to the IC device. Data Output Block (pin 12) Isolate the data output block sufficiently from the IF input block (pin 6). 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 13 and 14 too close to each other. Isolate the patterns connected to the input block (pin 13) and output block (pin 16) from each other. Make the RF input signal line relatively thin. Place a relatively wide ground pattern between the RF-IN pin (pin 13) and RF-DEC pin (pin 14). Connect the RF-OUT pin (pin 16) and MIX-IN pin (pin 18) 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 13) according to the board circuit pattern. IC Mounting Area Provide a ground pattern under the IC device, and prepare relatively many through holes.
