ATELLITE SYSTEMS
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.

Forothersatellitesystems,frequenciesofe.g.5.80, 6.60 or 6.65 MHzcanalsobereceived.A de-emphasisof60
μ
s,
or in accordance with J17, is available.
Main channels with high deviation can also be handled.
m/st/d = mono or stereo or dual language sound.
Adaptive de-emphasis is compatible to transmitter specification.
