Overview

TC9256, 57APG/AFG TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC9256APG, TC9256AFG, TC9257APG, TC9257AFG PLL for DTS The TC9256APG, TC9256AFG, TC9257APG and TC9257AFG are phase-locked loop (PLL) LSIs for digital tuning systems (DTS) with built-in two-modulus prescalers.

All functions are controlled through three serial bus lines.

These LSIs are used to configure high-performance digital tuning systems.

Key Features

  • Suitable for use in digital tuning systems in high-fi tuners and car stereos.
  • Built-in prescalers operate at an input frequency ranging from 30 to 150 MHz during FMIN input (with two-modulus prescaler) and at 0.5 to 40 MHz during AMIN input (with two-modulus prescaler or direct dividing).
  • 16-bit programmable counter, dual parallel output phase comparator, crystal oscillator and reference counter.
  • 3.6 MHz, 4.5 MHz, 7.2 MHz or 10.8 MHz crystal oscillators can.
