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 amplifie...
