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 2006-04-11 TA2030FNG Absolute Maximum Ratings (Ta = 25°C) Characteristic Supply voltage Power dissipation (Note) Symbol Rating Unit VCC 4.5 V PD 400 mW Operating temperature Topr −25~75 Storage temperature Tstg −55~150 °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 Cir− cuit ICC1 Supply current ICC2 1 Local oscillator voltage FM OSC buffer output voltage Local oscillator stop voltage Conversion gain TV GC1 a Test Condition Vin < −20bBµV EMF b ICC3 Conversion gain SW 1 2 Min.
