SA2104 - 3V AM/FMMPX TUNER

General Description

The SA2104/SA2104S are single-chip tuner ICs that incorporate FM/AM and MPX circuits, which are designed for portable radios and 3V headphone radios.

The SA2104/SA2104S are suitable for digital tuning system applications.

FM local oscillation voltage is set up low relativity, for NEW FCC.

Key Features

  • Operating supply voltage range: VCC=1.8~10V (Tamb=25°C).
  • For NEW FCC.
  • FM/AM and MPX integrated in a single-chip.
  • Build in FM/AM IF count buffer. FM: 1.3375MHz (1/8 dividing) AM: 450kHz.
  • Build in mute circuit for IF count output according to field strength.
  • Build in FM MPX VCO circuit.
  • Build in FM/AM OSC buffer output for DTS.
