Product data sheet
8.7.1 Narrow-band FM PLL 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.
I/Q output mode for zero IF conversion.
Conversion mode selection via synthesizer for DIF, TSS 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 and ZIF.
Symmetrical output stages for DIF, ZIF and 2nd SIF.
Second narrow-band 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.
Passive AM sound 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.
Weak signal processing for FM sound in the event of low or noisy FM carrier.
Weak signal processing includes noise dependent gain and bandwidth control.
