Overview
SC9256 PLL FOR DIGITAL TUNING SYSTEM DESCRIPTION The SC9256 is phase-locked loop (PLL) LSIs for digital tuning systems (DTS) with built in 2 modulus prescalers.
All functions ate controlled through 3 serial bus lines.
These LSIs are used to configure high-performance digital tuning system.
DIP-16-300-2.
54 FEATURES * Optimal for configuring digital tuning systems in high-fi tuners and car stereos.
* Built-in prescalers.
Operate at input frequency ranging from 30~150 MHz during FMIN input (with 2 modulus prescaler) and at 0.
5~40MHz during AMIN input (with 2 modulus prescaler or direct dividing).
* 16 bit programmable counter, dual parallel output phase comparator, crystal oscillator and reference counter.
* 3.
6MHz, 4.
5MHz, 7.
2MHz or 10.
8MHz crystal oscillators can be used.
* 15 possible reference frequencies.
( When using 4.
5MHz crystal) * Built-in 20 bit general-purpose counter for such uses as measuring intermediate frequencies (IFIN1 and IFIN2) * High-precision (±0.
55~±7.
