SC9256 Overview
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.
SC9256 Key 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
- 16 bit programmable counter, dual parallel output phase parator, 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
- High-precision (±0.55~±7.15µs)
