Product data sheet Rev. 02 — 27 November 2009 5 of 83 NXP Semiconductors TDA8295 Digital global standard low IF demodulator for analog TV and FM radio [1] 100 % ADC current; 100 % video DAC current; 50 % sound DAC current. [2] 100 % ADC current; 50 % video DAC current; 25 % sound DAC current. [3] The pull-in range can be doubled to ±1660 kHz by I2C-bus register like described in Table 16. Then the AFC read-out has 256 steps. 5. Ordering information BAF(−3dB) −3 dB AF bandwidth AM 20 27 - kHz FM 40 50 - kHz (S/N)w(AF) AF weighted signal-to-noise ratio via internal mono sound demodulator; “ITU-R BS.468-4”; FM mode related to 27 kHz deviation before pre-emphasis; 10 % residual PC; SC1 color bar picture 54 58 - dB via internal mono sound demodulator; “ITU-R BS.468-4”; AM; m = 54 %; 3 % residual PC; SC1 color bar picture 43 46 - dB Table 1. Quick reference data …continued Power supplies 3.3 V, 1.2 V; Tamb = 25 °C; PC / SC1 for L and M = 10 dB, all others 13 dB; residual picture carrier for L = 3 %, all others 10 %; FM/AM modulation = 54 %, 1 kHz modulation frequency; measured in application PCB (see Figure 15) with 16 MHz crystal frequency, loaded with 75 Ω (CVBS) and 1 kΩ (SSIF/audio). Values are meant for ‘easy programming’ settings (recommended) except internal mono audio and IF demodulation. The low IF spectrum is delivered by a professional downconverter.
