TDA6151-5 - Siemens Semiconductor

TDA6151-5 Satellite-Video IC

The demodulated FM-satellite video signal is fed via a buffer amplifier to a gain controlled amplifier. The gain control is done using an external applied DC-voltage. The output signal of this amplifier is used to drive three separate signal pathes. First of all the baseband is fed via a high pass filter with a cut off frequency of approx. 4 MHz to the input.

Features
