FEATURES
● 5 V supply voltage● Gain controlled wide band VIF-amplifier (AC-coupled)
● True synchronous demodulation with active carrier regeneration (very linear demodulation, good intermodulation figures, reduced harmonics, excellent pulse response)
● Robustness for over-modulation better than 105% due to gated phase detector at L/L accent standard
● VCO frequency switchable between L and L accent (alignment external) picture carrier frequency
● Separate video amplifier for sound trap buffering with high video bandwidth
● VIF-AGC detector for gain control, operating as peak sync detector for B/G and peak white detector for L (optional external AGC); signal controlled reaction time for L
● Tuner AGC with adjustable takeover point (TOP)
● AFC detector without extra reference circuit
● AC-coupled limiter amplifier for sound intercarrier signal
● Two alignment-free FM-PLL demodulators with high linearity
● SIF input for single reference QSS mode (PLL controlled); SIF AGC detector for gai...
