Pin 18 output waveform 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 10kΩ 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 10kΩ 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 4.7kΩ 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 – µCOM 3.15V Vcc 47k 4.75V VccH 8W 47k P52A 8W SI CK CS I1 SG64 SG62 V60 V59 V58 100µ 10k a b SW64 a 0.22µ 0.22µ 22µ b SW60 a b SW59 a b SW58 a 47µ 2.2µ 0.01µ 47µ 22µ 22µ 0.01µ b SW62 1k 120 1k 120 100µ TP55 I2 10k 10k 10k 10k a SW1 GNDH EPOUT L LINEO L MICIN L VCT5 64 b 1M LINEIN L 22µ a 2 1 100µ 22k LINE MIX ON/OFF (SI) REC/PB (CK) MIC/LINE (CS) PMUTETC VCC2 MIXOUT VCCH 63 VCC1 62 61 60 59 58 57 56 55 54 53 MUTEOUT 0.22µ SG2 b SW2 a FADE b SW3 V3 3 a MICIN R 4 0.22µ SG4 b SW4 10µ 47k 7 6 5 10µ 10µ 10µ 4.7µ RFDC R 8 IFDC L 9 GND1 10 WEIGHT R 11 NRDC R 12 0.22µ 14 13 1µ 22µ MUTE ON/OFF 52 EPLINEOUT R 51 50 49 34 35 36 37 38 39 40 41 42 82k 43 TP36 DC R ALCDET 2.2µ 22µ 0.22µ 44 1µ SW36 S HTC R LINEIN R 1k 0.22µ b NC a OUTSEL CTL (P.SAVE) TP16 470k 0.47µ P15 15 MONI R TP49 4.7µ a S HTC L TCH R 47k 4.7µ V36 VCTH b WEIGHT L 45 SW44 a NRDC L P37 GND2 46 SW46 b 1000p TCH L 47 a V46 V44 TC L 48 V48 1000p MONI L IFDC R DEVADJ L IREF NC RFDC L PLLLPF L TC R – 33 – V33 23 22 21 20 19 18 17 BPFMONI PBRFIN RF AGC TC MONOOUT PLLLPF R MONO TC SI/PA (SP/LP) b SW16 V16 16 82k 24 25 26 27 28 29 30 31 32 RECFMOUT VCT BPF ADJ MUTETC NTSC/PAL FSCIN NC RFSWP MATRIX CTL 33 DEVADJ R Electrical Characteristics Measurement Circuit c b 0.47µ SG22 V17 2200p 0.22µ V20 3300p 470k 100k Vcc a b SW23 Standard demodulator 10µ a SW26 b V26 SG29 SG31 680p a SW22 a 10k 0.01µ 4.7k 82k V28 TP26 0.01µ SW29 b a SW31 b V32 Standard modulator Vcc TP-P52 TP-P49 SG-R4 SG-R62 CXA1737R 1k VCC2 MIXOUT VCCH MUTEOUT EPLINEOUT R GNDH LINE IN Lch 0.22µ 0.22µ 22k 22µ 2 1 100µ LINEIN L 64 1M VCC1 63 MICIN L VCT5 61 62 LINE MIX ON/OFF (SI) 60 MIX ON/OFF (SI) MIC IN Lch REC/PB (CK) 59 REC/PB (CK) 22µ MIC/LINE (CS) 57 PMUTETC 56 55 54 53 52 51 50 EPOUT L 58 0.01µ 47µ 2.2µ 0.01µ 47µ 22µ 22µ ALCDET 0.22µ 4 3 0.22µ 10µ 47k 7 6 5 10µ RFDC R 8 10µ IFDC L 9 10µ GND1 10 WEIGHT R 11 4.7µ NRDC R 12 0.22µ 1µ 14 13 22µ MONI R 15 24 23 22 21 20 19 18 17 RECFMOUT BPFMONI PBRFIN RF AGC TC MONOOUT PLLLPF R MONO TC SI/PA (SP/LP) 16 0.01µ 0.47µ 0.22µ SI/PA (SP/LP) 2200p 470k 3300p PB RF IN 10µ BPF ADJ 680p NTSC/PAL Fsc IN RF SWP MATRIX CTL Application circuits shown are typical examples illustrating the operation of the devices.
