TOSHIBA TA31136F,TA31136FN 4. Demodulation output distortion factor Demodulation output distortion factor is about -43dB when ceramic discriminator CDB450C24 used, is about -50dB when coil 5114-JPS-010 used. (IF 100dBV EMF input, measured pin 9 before when input from MIX demodulation output distortion factor depends largely on a ceramic filter band and a group delay characteristic. Select ceramic filter adequately. 5. INVERTER AMP usage The INVERTER AMP can be used to form a band pass filter as shown in Figure 4. Set constants as in equations (1) to (3). However, because a low pass filter and a high pass filter are built in, it is recommended that center frequency fg be about 30kHz.

Noise detection rise time The rise time is a proportion of time constant 7.5ms of the smoothing capacitor Cg =0. 1F of the noise rectifier and internal resistor 75kQ.. Although decreasing the capacitance of Cg can shorten the rise time, note that the noise detection output fluctuation may increase. This should be taken into account before use. 1997-03-25 5/16

TOSHIBA TA31136F,TA31136FN 7. RSSI function A DC voltage corresponding to the input level of IF input pins (pin 5) is output to the RSSI pin (P21). While the linear range is about 80dB when Vcc=2V, the range can be expanded to 80dB as in Figure 6. However, in such a case, note that the temperature characteristics of the RSSI output may alter due to a disparity between the temperature coefficient of the external resistor and the internal resistance of the IC.
