Product data sheet
8.7.1 FM PLL narrowband demodulation
8.7.2 AM sound demodulation
8.6 DIF/SIF converter stage
8.7 Mono sound demodulator
8.8 Audio amplifier
Frequency conversion with sideband suppression.
Selection mode of upper or lower sideband for pass or suppression.
Suppression around zero for frequency conversion.
Conversion mode selection via synthesizer for DIF and radio mode or via VIF Frequency
Phase-Locked Loop (FPLL) for TV QSS sound (FM/AM).
External BP filter (e.g. for 4.5 MHz) for additional filtering, optional.
Bypass mode selection for use of external filter.
Integrated SIF BP tracking filter for chroma suppression.
Integrated tracking filters for LIF.
Symmetrical output stages for direct IF, LIF and 2nd SIF (intercarrier signal).
Second narrowband gain control loop for 2nd SIF via FM PLL.
Additional external input for either TV or radio intercarrier signal.
FM carrier selection independent from VIF trap, because VIF trap uses reference via
synthesizer.
FM wide and ultra wide mode with adapted loop bandwidth and different selectable
FM acquisition window widths to cope with FM overmodulation conditions.
AM sound envelope detector.
L and L-accent standard without SAW switching (done by sideband selection of SIF
converter).
Different gain settings for FM sound to adapt to different FM deviation.
Switchable de-emphasis for FM sound.
Automatic mute function when FM PLL is unlocked.
Forced mute function.
Output amplifier for AM sound.
