21 / 58 page  2004 Aug 25 21 Philips Semiconductors Product specification I2C-bus controlled multistandard alignment-free IF-PLL demodulator with FM radio TDA9887 Table 17 Frequency selection bits Notes 1. Pin SIOMAD can be used for the selection of the different NTSC standards without I2C-bus. With a resistor on pin SIOMAD, fVIF = 58.75 MHz; without a resistor on pin SIOMAD, fVIF = 45.75 MHz (NTSC-M). 2. Attention: video sound traps are locked on the FM VCO. The second VIF should be selected in accordance with the selected video standard. Table 18 Data setting after power-on reset (default setting with a resistor on pin SIOMAD) Table 19 Data setting after power-on reset (default setting without a resistor on pin SIOMAD) BIT DESCRIPTION E4 E3 E2 TV MODE BIT B3 = 0 OF REGISTER SAD = 00 RADIO MODE BIT B3 = 1 OF REGISTER SAD = 00 000 fVIF = 58.75 MHz; note 1 fRIF1 = 33.3 MHz, fVCO = 44 MHz; fRIF2 = 10.7 MHz 001 fVIF = 45.75 MHz; note 1 fRIF1 = 41.3 MHz, fVCO = 52 MHz; fRIF2 = 10.7 MHz 010 fVIF = 38.9 MHz fRIF1 = 33.3 MHz, fVCO = 44 MHz; fRIF2 = 10.7 MHz 011 fVIF = 38.0 MHz fRIF1 = 41.3 MHz, fVCO = 52 MHz; fRIF2 = 10.7 MHz 100 fVIF = 33.9 MHz fRIF1 = 33.3 MHz, fVCO = 44 MHz; fRIF2 = 10.7 MHz 101 fVIF = 33.4 MHz fRIF1 = 33.3 MHz, fVCO = 44 MHz; fRIF2 = 10.7 MHz 110 fVIF = 45.75 MHz plus FM external input via pin FMIN; note 2 fRIF1 = 33.3 MHz, fVCO = 44 MHz; fRIF2 = 10.7 MHz 111 fVIF = 38.9 MHz plus FM external input via pin FMIN; note 2 fRIF1 = 33.3 MHz, fVCO = 44 MHz; fRIF2 = 10.7 MHz REGISTER MSB LSB D7 D6 D5 D4 D3 D2 D1 D0 Switching mode 11010110 Adjust mode 00110000 Data mode 00000000 REGISTER MSB LSB D7 D6 D5 D4 D3 D2 D1 D0 Switching mode 11010110 Adjust mode 00110000 Data mode 00000100 |
