FS8108 - Low Power Phase-Locked Loop IC

Datasheet Summary

Description

The FS8108 is a serial data input, phase-locked loop IC with programmable input and reference frequency dividers.

When combined with a VCO, the FS8108 becomes the core of a very low power frequency synthesizer well-suited for mobile communication applications such as paging systems.

Features

  • ‹ High maximum input operating frequency.
  • 185 MHz at VDD1 = 1.0 V ‹ Up to 22 MHz internal crystal oscillator reference frequency at VDD1 = 1.0 V ‹ Extremely low current consumption (IDD,total typically 0.4 mA at fFIN = 90 MHz) ‹ 18-bit programmable input frequency divider (including a ÷ 64/65 prescaler) with divide ratio range from 4032 to 262143 ‹ 13-bit programmable reference frequency divider (including a ÷ 8 prescaler) with divide ratio range from 40 to 65528 ‹ Optional lock detecto.
