TDA8296
Digital global standard low IF demodulator for analog TV and FM radio
Table 64. Characteristics …continued
Power supplies 3.3 V, 1.2 V; T_amb = 25 °C; PC/SC1 for L and M = 10 dB, all others 13 dB; nominal residual picture carrier of
3 % for L/L’ , 10 % for M, 10 % for B/G, 12.5 % for D/K, 20 % for I; FM/AM modulation = 54 %, 1 kHz modulation frequency;
measured in application PCB (see Figure 22 and Figure 23) with 16 MHz crystal frequency, terminated with 75 Ω (CVBS) and
1 kΩ (SSIF/audio). Operation mode set via easy programming (Section 9.3.1), otherwise stated. Low IF input signal at -3dB
full scale, input frequencies as defined under row header IF input.
