SAA1057 - Radio tuning PLL frequency synthesizer

General Description

The SAA1057 is a single chip frequency synthesizer IC in I2L technology, which performs all the tuning functions of a PLL radio tuning system.

The IC is applicable to all types of radio receivers, e.g.

car radios, hi-fi radios and portable radios.

Key Features

  • On-chip prescaler with up to 120 MHz input frequency.
  • On-chip AM and FM input amplifiers with high sensitivity (30 mV and 10 mV respectively).
  • Low current drain (typically 16 mA for AM and 20 mA for FM) over a wide supply voltage range (3,6 V to 12 V).
  • On-chip amplifier for loop filter for both AM and FM (up to 30 V tuning voltage). QUICK.
