Product Overview

The LTC6908IDCB-1#PBF is an easy-to-use Precision Oscillator provides 2-outputs, shifted by either 180 or 90°. The oscillator frequency is programmed by a single external resistor (RSET) and spread spectrum frequency modulation (SSFM) can be activated for improved electromagnetic compatibility (EMC) performance. The LTC6908 operates with a single 2.7 to 5.5V supply and provides rail-to-rail, 50% duty cycle square wave outputs. A single resistor from 10k to 2M is used to select an oscillator frequency from 50kHz to 10MHz (5V supply). The LTC6908's SSFM capability modulates the output frequency by a pseudorandom noise (PRN) signal to decrease the peak electromagnetic radiation level and improve EMC performance. The amount of frequency spreading is fixed at ±10% of the centre frequency. When SSFM is enabled, the rate of modulation is selected by the user. The three possible modulation rates are fOUT/16, fOUT/32 and fOUT/64.
  • Complementary outputs (0/180°)
  • One external resistor sets the frequency
  • Outputs muted until stable
  • ±10% Frequency spreading
  • ±40ppm/°C Temperature stability
  • 260µs Typical fast start-up time (1MHz)
  • 400µA Typical supply current (V+=5V, 50kHz)
