... These secondary carrier frequencies can be in the range of 6.30 to 8.28 MHz. The TDA8742; H contains all circuitry for processing the main channel and for two secondary channels, from baseband signal to line (SCART) output drivers. The desired frequencies can be routed to the device via bandpass filters ...
