The reference voltage has a low temperature coefficient and high line regulation. 2.5.2 DVB-IF Input Amplifier, AGC The filtered IF signal is fed to the balanced input pins IF1 / IF2 of the gain controlled amplifier, where it is amplified and then down converted to the output frequency signals. The control voltage for the gain-controlled amplifier at pin IFAGC is applied from external source. If the IFAGC control voltage level exceeds an adjustable value (TAGCthr), a sink current at TunAGC is generated which controls the tuner gain. 2.5.3 Oscillator The symmetrical 4 pin voltage controlled oscillator feeds the mixer to generate the down converted DVB-IF signals.The frequency of the VCO is below or above the input frequency of the AGC amplifier. The control voltage for the external varactor diode is derived from the DVB processor. 2.5.4 Mixer and Output Buffers The mixer converts the filtered and amplified IF signal down to the low IF frequency. This frequency is fed to a balanced output pair OUT1 and OUT2.
