· Multi-standard vision IF circuit with alignment-free PLL demodulator
· Internal (switchable) time-constant for the IF-AGC circuit
· A choice can be made between versions with mono intercarrier sound FM demodulator and versions with QSS IF amplifier.
· The mono intercarrier sound versions have a selective FM-PLL demodulator which can be switched to the different FM sound frequencies (4.5/5.5/6.0/6.5 MHz). The quality of this system is such that the external band-pass filters can be omitted.
