SC9257S - PLL FOR DIGITAL TUNING SYSTEM

This page provides the datasheet information for the SC9257S, a member of the SC9257 PLL FOR DIGITAL TUNING SYSTEM family.

Datasheet Summary

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.

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: 0.5 to 40 MHz ( with 2 modulus prescaler or direct dividing ).
  • 16-bit programmable counter, dual parallel output phase.
  • Turns off FM, AM and IF amps when Standby mode function comparator, crystal oscillator and reference counter.
  • Serial data input and interface.
  • Uses 3.6MHz, 4.5MHz, 7.2MHz or 10.8MH.
