Description



Features:

5V supply voltage
Applicable for Intermediate Frequencies (IFs) of
38.9,45.75and58.75MHz
Gain controlled wide band VideoIF (VIF) amplifier (AC-coupled)
True synchronous demodulation with active carrier
regeneration (very linear demodulation, good
intermodulation figures, reduced harmonics and
excellentpulse response)
Robustness for over-modulation better than 105% due
to gated phase detector at L/Laccent standard and
PLL-bandwidthcontrolatnegativemodulatedstandards
Voltage Controlled Oscillator (VCO) frequency
switchablebetweenLandLaccent(alignmentexternal) picture carrier frequency
VIF Automatic Gain Control (AGC) detector for gain
control, operating as peak sync detector for B/G, peak
whitedetectorforL;signalcontrolledreactiontimeforL
Tuner AGC with adjustable TakeOver Point (TOP)
Automatic Frequency Control (AFC) detector without extra reference circuit
