TDA9897; TDA9898
Multistandard hybrid IF processing
8.6 DIF/SIF converter stage
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 lter (e.g. for 4.5 MHz) for additional ltering, optional.
Bypass mode selection for use of external lter.
Integrated SIF BP tracking lter for chroma suppression.
Integrated tracking lters 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.
8.7 Mono sound demodulator
8.7.1 FM PLL narrowband demodulation
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.
8.7.2 AM sound demodulation
AM sound envelope detector.
L and L-accent standard without SAW switching (done by sideband selection of SIF
converter).
8.8 Audio amplier
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 amplier for AM sound.
