An important specification for satellite TV reception is the Astra specification. The TDA9874A is suitable for the reception
of Astra and other satellite signals, with sound carrier frequencies from 4 to 9.2 MHz.
Table 4 FM satellite sound
Notes
1. For other satellite systems, frequencies of e.g. 5.80, 6.60 or 6.65 MHz can also be received. A de-emphasis of 60 s,
2. Main channels with high deviation can also be handled.
3. m/st/d = mono or stereo or dual language sound.
4. Adaptive de-emphasis is compatible to transmitter specification.
