Product specification
Single/multistandard VIF/SIF-PLL and
FM-PLL/AM demodulators
FEATURES
•
5 V supply voltage
•
Applicable for Intermediate Frequencies (IFs) of
38.9, 45.75 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 and
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
•
Voltage Controlled Oscillator (VCO) frequency
switchable between L and L accent (alignment external)
picture carrier frequency
•
VIF Automatic Gain Control (AGC) 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)
•
Automatic Frequency Control (AFC) detector without
extra reference circuit
