100MHz Input Mixer and 450kHz FM/AM IF Demodulator IC

  • Wide Operating Voltage (2.2V to 9.0V)
  • Low Operating Current (FM: 2.5mA at V+ =2.7V, AM SW =Low / AM and FM: 5mA at V+ =2.0V, AM SW =High)
  • Maximum Mixer Input Frequency (100MHz (reference value))
  • IF Frequency (450kHz (standard))
  • AM/FM detector circuits selectable (AM SW= High : Simultaneous operation of AM/FM sections / AM SW= Low : FM section only)
  • Built-in AGC circuit in AM section
  • Bipolar Technology
  • Package Outline (SSOP20)
  • Wide Range RSSI (Received Signal Strength Indication)
