Product specification
Digital TV Sound Processor (DTVSP)
TDA9870A
2.1.2
S
ATELLITE 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
μ
s, or in accordance with J17, is available.
m/st/d = mono or stereo or dual language sound.
Adaptive de-emphasis is compatible to transmitter specification.
