When adjusting DEV, connect a 10 k load resistor between Pin 24 and GND. * Reference modulation distortion factor Demodulate the Pin 24 output into the audio signal with the reference demodulator under the same conditions as for DEV adjustment above, then measure the distortion factor. * BPF f0 adjustment method Input 15 mVp-p, 1.4 MHz and 1.6 MHz signals to Pin 22 and adjust the voltage applied to Pin 26 so that the 1.4 MHz and 1.6 MHz levels output to Pin 23 are equal. Note that since adjustment OFF mode results when the Pin 26 voltage is between 0 to 0.8 V, the BPF f0 should be adjusted with the Pin 26 voltage between 1.2 to 3 V (when VCC1 = 3.15 V). When adjusting the BPF f0, connect a 4.7 k load resistor between Pin 23 and GND. --24-- CXA2038R Mode Control Tables Parallel CTL mode table Pin CTL voltage Symbol No. LOW (0 to 1 V) OPEN HIGH1 (2 V to VCC1) HIGH2 (2 V to 3.5V) HIGH3 (4.3 V to VCCH) 17 SP/LP LP SP -- SP SERIAL1 28 NTSC/PAL PAL -- NTSC -- -- 33 BPF ON/OFF BPF ON BPF ON -- BPF ON 1.5 MBPFOFF 48 MUTE MUTE OFF MUTE ON MUTE ON -- -- 58 MIC/LINE LINE LINE MIC -- -- 59 REC/PB REC REC PB -- -- 1 When Pin 17 is 4.3 V or more, the IC operates in serial control mode.
