TDA8295
Digital global standard low IF demodulator for analog TV and FM radio
Table 1. Quick reference data â¦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 âeasy programmingâ
settings (recommended) except internal mono audio and IF demodulation. The low IF spectrum is delivered by a professional
downconverter.
