Product Details

Description



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
