TDA8742; TDA8742H
APPLICATION INFORMATION
General
This application is mainly intended to have more than two
inputs for secondary channel available. In this event a
choice between the same frequency sets e.g. 10.7 and
10.52 MHz but with different bandwidths is possible. A
narrow bandwidth can be chosen in the event of a weak
signal, however this produces slightly more distortion. A
normal signal will be processed using 150 kHz filters thus
resulting in a signal with normal distortion. For the main
channel either baseband or synthesized signal can be
selected. The circuit is illustrated in Fig.5.
