Product Overview

The LTC6900IS5#PBF is a Low Power 1kHz to 20MHz Resistor Set Oscillator that is easy to use and occupies very little PC board space. The oscillator frequency is programmed by a single external resistor (RSET). The LTC6900 has been designed for high accuracy operation (<=1.5% frequency error) without the need for external trim components. The LTC6900 operates with a single 2.7 to 5.5V power supply and provides a rail-to-rail, 50% duty cycle square wave output. The CMOS output driver ensures fast rise/fall times and rail-to-rail switching. The frequency-setting resistor can vary from 10kR to 2MR to select a master oscillator frequency between 100kHz and 20MHz (5V supply). The three-state DIV input determines whether the master clock is divided by 1, 10 or 100 before driving the output, providing three frequency ranges spanning 1kHz to 20MHz (5V supply).
  • One external resistor sets the frequency
  • 1kHz to 20MHz Frequency range
  • 500µA Typical supply current (VS = 3V, 3MHz)
  • <=1.5% Maximum frequency error (5kHz to 10MHz, TA = 25°C)
  • <=2% Maximum frequency error (5kHz to 10MHz, TA = 0 to 70°C)
  • ±40ppm/°C Temperature stability
  • 0.04%/V Supply stability
  • 50% ±1% Duty cycle (1kHz to 2MHz)
  • 50% ±5% Duty cycle (2 to 10MHz)
  • Fast start-up time (50µs to 1.5ms)
  • 100R CMOS output driver
  • Operates from a single-supply
