Multistandard vision and sound-IF PLL with DVB-IF processing
FEATURES 5 V supply voltage Applicable for IF frequencies of 38.9 MHz and 45.75 MHz Two switched VIF inputs, gain controlled wide band VIF-amplifier (AC-coupled) True synchronous demodulation with active carrier regeneration (very linear demodulation, good intermodulation figures, reduced harmonics and excellent pulse response) VCO frequency switchable between TV (M or BG/L) IF-picture carrier and Digital Video Broadcast (DVB) frequency Separate video amplifier for sound trap buffering with high video bandwidth VIF AGC detector for gain control, operating as peak sync detector for M and B/G and peak white detector for L; controlled reaction time for L Tuner AGC with adjustable takeover point (TOP) AFC detector without extra reference circuit SIF input for single reference QSS mode (PLL controlled); SIF AGC detector for gain controlled SIF amplifier; single reference QSS mixer able to operate in high performance single reference QSS mode AC-coupled limiter amplifier for sound intercarrier signal Alignment-free FM-PLL demodulator with high linearity AM demodulator without extra reference circuit Stabilizer circuit for ripple rejection and to ach...
