Fig. 4 - 31 - CXA1737R Adjustment and Measurement Methods DEV adjustment method * Lch adjustment Input the reference input (-38dBm/400Hz) to the MIC input (Pin 62) and adjust the voltage applied to Pin 36 (V36) so that the Pin 24 output reference frequency deflection is 1.5MHz 60kHz. When adjusting DEV, connect a 10k load resistor between Pin 24 and GND as shown in the electrical characteristics measurement circuit. * Rch adjustment Input the reference input (-38dBm/400Hz) to the MIC input (Pin 4) and adjust the voltage applied to Pin 16 (V16) so that the Pin 24 output reference frequency deflection is 1.7MHz 30kHz. When adjusting DEV, connect a 10k load resistor between Pin 24 and GND as shown in the electrical characteristics measurement circuit. Reference FM modulation distortion factor measuring method 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 adjustment method Input 15mVp-p, 1.625MHz signal to Pin 22 and adjust the voltage applied to Pin 26 (V26) so that the output level when the SW of Pin 23 is switched to "a" (1.7M BPF output) and the output level when the SW of Pin 23 is switched to "b" (1.5M BPF output) are equal. When adjusting BPF, connect a 4.7k load resistor between Pin 23 and GND as shown in the electrical characteristics measurement circuit. Fader adjustment method Input the reference input (-38dBm/ 400Hz) to the MIC input (Pins 62 and 4) and adjust the output level of Pins 49 and 52 with the voltage applied to Pin 3 (V3). - 32 - Electrical Characteristics Measurement Circuit P37 1000p SW36 a a V48 SW46 82k 36 34 33 NC 35 48 47 NC DC R VCTH GND2 TCH L TC L 44 42 41 39 46 45 43 38 40 37 SW44 TP36 4.7 1 4.7 0.22 22 470k V33 b a b 0.22 b 0.47 V46 V44 1000p V36 S HTC R S HTC L NRDC L MONI L WEIGHT L DEVADJ L PLLLPF L TP49 V32 MATRIX CTL SW31 b RFSWP a SG31 51 GNDH NC 30 31 32 47k 49 LINEO L 2.2 8W 50 EPOUT L 120 22 10k P52A 1k 47k 52 EPLINEOUT R FSCIN 29 0.01 10k OUTSEL CTL (P.SAVE) 10k MUTE ON/OFF 1k SW29 b a SG29 V28 53 MUTEOUT NTSC/PAL 28 8W 120 22 10k 47 54 VCCH MUTETC 27 TP26 680p b 55 MIXOUT BPF ADJ 26 82k a SW26 VCT 25 10 TP-P49 RECFMOUT 24 10k b SW23 58 MIC/LINE (CS) BPFMONI 23 4.7k a SW22 a 59 REC/PB (CK) PBRFIN 22 0.01 c SG-R62 b Standard modulator RF AGC TC 21 Vcc 100k 61 VCT5 MONOOUT 20 V20 470k 62 MICIN L PLLLPF R 19 0.22 63 VCC1 MONO TC 18 2200p 0.47 3300p SG-R4 SG22 Vcc Standard demodulator TP-P52 V26 VccH I2 4.75V 100 TP55 0.01 1k 47k 2.2 10k 56 VCC2 47 Vcc I1 3.15V 57 PMUTETC 100 RFDC L MICIN R ALCDET IREF IFDC L NRDC R FADE RFDC R WEIGHT R TC R MONI R IFDC R LINEIN R GND1 1 2 3 4 5 6 7 8 9 10 11 12 13 TCH R 14 15 16 82k 0.22 TP16 SW4 10 47k 10 10 10 4.7 0.22 1 22 SW16 0.22 22k SW2 22 100 a b a b 1M b SW3 a SW1 a b a SG4 V3 P15 DEVADJ R - 33 - 60 LINE MIX ON/OFF (SI) 64 LINEIN L SG2 0.01 CS a V58 b SW58 COM CK a V59 b SW59 SI a V60 b SW60 22 SG62 a b SW62 0.22 SG64 a SI/PA (SP/LP) 17 V17 b SW64 0.22 b CXA1737R V16 Application Circuit 0.47 0.22 470k 1000p 1000p 4.7 0.22 1 4.7 22 DEV ADJ Lch MUTE ON/OFF 48 47 34 PLLLPF L NC DC R VCTH GND2 TCH L TC L S HTC R S HTC L NRDC L MONI L WEIGHT L DEVADJ L NC 44 42 41 39 33 36 46 45 43 38 40 37 35 OUTSEL CTL (P.
