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.
2. Main channels with high deviation can also be handled.
3. A de-emphasis of 60 s, or in accordance with J17, is available.
4. m/st/d = mono or stereo or dual language sound.
5. Adaptive de-emphasis is compatible to transmitter specification.
