PW SW It is necessary to connect an external pull−down resistor with the terminal PW SW (pin(7)), in case that this IC is turned on due to external noise etc. 2. MODE SW It is necessary to connect an external pull−down resistor with the terminal MODE SW (pin(6)), in case that this IC doesn't operate normally due to external noise etc. 3. RF GND This IC has two GND terminals (pin(3): RF GND, pin(16): GND). External parts shown in below should be connected with RF GND (pin(3)), and other parts should be connected with GND (pin(16)). ・ By−pass capacitor at pin(14) (FM RF) and pin(15) (TV RF) ・ By−pass capacitor at pin(4) (FM BY) and pin(2) (TV BY) The pattern diagram of capacitor connected with pin(2) and pin(4) should be shortly, because RF circuit and MIX circuit operate on the voltage of pin(2) or pin(4). 4 2004-11-17 TA2030FNG Maximum Ratings (Ta = 25°C) Characteristic Supply voltage Power dissipation Operating temperature Storage temperature (Note) Symbol VCC PD Topr Tstg Rating 4.5 400 −25~75 −55~150 Unit V mW °C Note: Derated above Ta = 25°C in the proportion of 3.2mW / °C Electrical Characteristics Unless Otherwise Specified, VCC = 1.2V, Ta = 25°C, fFM = 92MHz, fTV = 200MHz ∆f = ± 22.5kHz, fm = 1kHz, SW 2 : b Characteristic Symbol ICC1 Supply current ICC2 ICC3 Conversion gain Local oscillator voltage FM OSC buffer output voltage Local oscillator stop voltage Conversion gain Local oscillator voltage TV OSC buffer output voltage Local oscillator stop voltage Power on current Power off voltage TV mode on current FM mode on voltage GC1 VOSC1 VBUF1 VSTP1 GC2 VOSC2 VBUF2 VSTP2 I7 V7 1 I6 V6 d c a a VCC = 0.95V, V2 ≤ 0.2 V SW2: d V4 ≥ 0.4 V VCC = 0.95V, V2 ≤ 0.2 V SW2: c V4 ≤ 0.2 V VCC = 0.95V, V2 ≥ 0.4 V V4 ≤ 0.2 V VCC = 0.95V, V2 ≤ 0.2 V V4 ≥ 0.4 V 3 b fosc = 165MHz 2 Vin = 65dBµV EMF 3 a fosc = 65MHz 2 1 Test Cir− cuit SW 1 Test Condition IC OFF, SW2: a Vin < −20bBµV EMF Vin = 65dBµV EMF FM mode TV mode Min. ― ― ― 29 ― ― ― 25 ― ― ― 5 0 5 0 Typ. 0.1 4.4 6.3 33 360 50 0.89 29 180 22 0.86 ― ― ― ― Max. 5 6.6 9.5 ― ― ― 0.95 ― ― ― 0.95 ― 0.3 ― 0.3 mVrms mVrms Unit µA mA dB a b V dB V µA V µA V 5 2004-11-17 TA2030FNG Test Circuit 1 Test Circuit 2 GC(dB) = 20ℓog VIF(µVrms) − (Vin(dBµV EMF) −6dB) TV / FM Separator: GTVS05(SOSHIN ELECTRIC CO., LTD.) 6 2004-11-17 TA2030FNG Test Circuit 3 Coil Data (test circuit) Coil No. L1 TV RF L2 FM RF L3 TV OSC L4 FM OSC T FM IFT Test Freq. 100MHz 100MHz 100MHz 100MHz 10.7MHz C0 (pF) ― ― ― ― 82 Q0 55 90 55 90 45 1 1 Turns 1−3 1/4 ― 1/4 ― 18 3 3 1−4 ― 1/2 ― 1/2 ― Wire (mmφ) 0.5UEW 0.5UEW 0.5UEW 0.5UEW 0.09UEW Reference (S) 0258−250 (S) 0258−238 (S) 0258−250 (S) 0258−238 (S) 4162−083A (S) : Sumida electric CO., LTD 7 2004-11-17 TA2030FNG 8 2004-11-17 TA2030FNG 9 2004-11-17 TA2030FNG Package Dimensions Weight: 0.09g (typ.) 10 2004-11-17 .
