General Description

The SC9257 is phase-locked loop (PLL) LSIs for digital tuning systems (DTS) with built in 2 modulus prescalers.

The LSIs are used to configure high-performance digital tuning systems, such as radio/cassette players.

They allow high-performance AM/FM tuners to be implemented easily DIP-20-300-2.54
