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 2002-10-30 TA2030FN Maximum Ratings (Ta = 25°C) Characteristic Symbol Rating Unit VCC 4.5 V PD 400 mW Operating temperature Topr -25~75 Storage temperature Tstg -55~150 Supply voltage Power dissipation (Note) °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 Test Circuit ICC1 Supply current ICC2 1 GC1 Local oscillator voltage VOSC1 FM OSC buffer output voltage TV VBUF1 Local oscillator stop voltage VSTP1 Conversion gain GC2 Local oscillator voltage VOSC2 OSC buffer output voltage VBUF2 Local oscillator stop voltage VSTP2 a Test Condition Vin < -20bBµV EMF b ICC3 Conversion gain SW 1 2 3 Typ.
