Low Jitter Voltage Controlled Crystal Oscillators (VCXOs)

Silicon Labs' low jitter voltage controlled oscillators (VCXOs) offer the industry’s shortest lead times, excellent jitter performance, high reliability, and superior Vc gain linearity, making them ideal for applications such as networking equipment, base stations, storage area networks and broadcast video systems. Devices in this family offer single, dual, quad, and I2C-controlled configurations and support a frequency range between 10 MHz and 1.4 GHz with a typical phase jitter of 0.5 ps. Taking advantage of patented DSPLL® technology, these devices use one fixed crystal and Silicon Labs’ proprietary DSPLL synthesizer to generate any frequency across this range. This solution also provides superior supply noise rejection, simplifying low jitter clock generation in noisy environments.

Features

  • Wide frequency range: 10 MHz to 1.4 GHz
  • Excellent jitter performance: 0.5 ps rms
  • Superior initial accuracy
  • Best-in-class control voltage linearity
  • Dual, quad and any frequency configurations available
  • Available with LVPECL, LVDS, CML, HCSL, or LVCMOS outputs
  • Operates with 1.8, 2.5, or 3.3 V supplies
  • Industry-standard, RoHS-compliant package and pinout:
    • 5 mm x 7 mm
  • Output enabled active high/active low polarity versions available
