1. 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 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 (24 kΩ)) R15 R12 C14 C15 1200 bps 43 k Ω 68 k Ω 4700 pF 1500 pF 2400 bps 43 k Ω 68 k Ω 2200 pF 680 pF 4800 bps 43 k Ω 68 k Ω 1000 pF 390 pF 9600 bps 43 k Ω 68 k Ω 470 pF 180 pF In addition, the current AM bit rate filter can be used as a tertiary 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 (24 kΩ)) R15 R13 R12 C14 C15 C18 1200 bps 43 k Ω 68 k Ω 68 k Ω 0.01 µF 560 pF 3300 pF 2400 bps 43 k Ω 68 k Ω 68 k Ω 4700 pF 270 pF 1500 pF 4800 bps 43 k Ω 68 k Ω 68 k Ω 2200 pF 150 pF 680 pF 9600 bps 68 k Ω 68 k Ω 68 k Ω 1200 pF 68 pF 390 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 bi t 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 resi stance 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 ci rcuit block, and connect th e 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.
