Digital TV Sound Processor (DTVSP)

TDA9870A

2.1.2

SATELLITE SYSTEMS

An important specification for satellite TV reception is the

“Astra specification”. The TDA9870A is suited for the reception

of Astra and other satellite signals.

Table 3

FM satellite sound

Notes

1. For other satellite systems, frequencies of, for example, 5.80, 6.60 or 6.65 MHz can also be received. A de-emphasis

of 60

µs, or in accordance with J17, is available.

2. m/st/d = mono or stereo or dual language sound.

3. Adaptive de-emphasis is compatible to transmitter specification.
