Features

  • 5 V supply voltage
  • Gain controlled wideband Vision Intermediate Frequency (VIF) amplifier; AC-coupled
  • Multistandard true synchronous demodulation for negative modulated standards with active carrier regeneration: very linear demodulation, good intermodulation figures, reduced harmonics and excellent pulse response
  • Fully integrated VIF Voltage Controlled Oscillator (VCO), alignment-free, frequencies switchable via logic pin VIF0 and pin QSSO with resistor
  • Digital acquisition help circuit, VIF frequencies of 38.0 MHz, 38.9 MHz, 45.75 MHz and 58.75 MHz
  • 4 MHz reference frequency input signal from Phase-Locked Loop (PLL) tuning system or operating as crystal oscillator
  • VIF Automatic Gain Control (AGC) detector for gain control; operating as peak sync detector
  • VIF AGC monitor output at pin VAGC
  • Precise fully digital Automatic Frequency Control (AFC) detector with 4-bit digital-to-analog converter
  • TakeOver Point (TOP) adjustable with potentiometer
  • Fully integrated sound carrier trap for 4.5 MHz, 5.5 MHz, 6.0 MHz and 6.5 MHz; controlled by FM PLL oscillator
  • Sound IF (SIF) input for single reference Quasi Split Sound (QSS) mode; PLL controlled
  • SIF AGC for gain controlled SIF amplifier; single reference QSS mixer able to operate in high performance single reference QSS mode or in intercarrier mode; switchable via SIF input pins
  • Alignment-free selective FM PLL demodulator with high linearity and low noise.
