Product Overview

The LTC6905HS5#TRMPBF is a precision programmable Silicon Oscillator for use with ceramic oscillator replacement. It is easy to use and occupies very little board space. It requires only a single resistor to set the output frequency from 17 to 170MHz with a typical frequency error of 0.5% or less. The LTC6905 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. Operation is simple: A single resistor, RSET, between 10 to 25k is used to set the frequency and an internal three-state divider (DIV input) allows for division of the master clock by 1, 2 or 4, providing three frequencies for each RSET value. It features a proprietary feedback loop that linearizes the relationship between RSET and frequency, eliminating the need for tables to calculate frequency.
  • One external resistor sets the frequency
  • CMOS output drives 500R load (VS=3V)
  • 100µs Typical fast start-up time
  • ±20ppm/°C Temperature stability
  • 0.5ns, CL=5pF Rise time
  • 7.2ps RMS at 170MHz Timing jitter
  • 6mA at fOSC=100MHz Typical supply current
