Overview
SC9257 PLL FOR DIGITAL TUNING SYSTEM 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 FEATURES * Available in DIP20, SOP20 packages.
* High speed programmable dividers.
SOP-20-300-1.
27 — FMIN: 30 to 150 MHz (with 2 modulus prescaler) — AMIN: 0.
