FEATURES
● 5 V supply voltage● Applicable for IFs (Intermediate Frequencies) of 38.9 MHz, 45.75 MHz and 58.75 MHz
● Gain controlled wide band Video IF (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 and PLL-bandwidth control at negative modulated standards
● VCO (Voltage Controlled Oscillator) frequency switchable between L and L accent (alignment external) picture carrier frequency
● VIF AGC (Automatic Gain Control) detector for gain control, operating as peak sync detector for B/G, peak white detector for L; signal controlled reaction time for L
● Tuner AGC with adjustable TakeOver Point (TOP)
● AFC (Automatic Frequency Control) detector without extra reference circuit ORDERING INFORMATION PACKAGE TYPE NUMBER NAME TDA9817 TDA9818 SDIP24 S...
