Qty: 1

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, and can also be used in both FM / AM transmitters.

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).
