SC9256 - PLL FOR DIGITAL TUNING SYSTEM

General 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.

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 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.
