ICD2053B - Programmable Clock Generator

Description

The ICD2053B Programmable Clock Generator offers a fully user-programmable phase-locked loop in a single 8-pin package.

The output may be changed “on the fly” to any desired frequency value between 391 kHz and 100 MHz (90 MHz at CMOS levels).

Features

  • Clock outputs ranging from 391 kHz to 100 MHz (TTL levels) or 90 MHz (CMOS levels).
  • 2-wire serial interface facilitates programmable output frequency.
  • Phase-Locked Loop oscillator input derived from external reference clock (1 MHz to 25 MHz) or External Crystal (2 MHz to 24 MHz).
  • Three-State output control disables output for test purposes.
  • Sophisticated internal loop filter requires no external components or manufacturing tweaks as commonly required.
