The 843441 is a low jitter, high performance clock generator. The 843441 is designed for use in applications using the SAS and SATA interconnect. The 843441 uses an external, 25MHz, parallel resonant crystal to generate four selectable output frequencies: 75MHz, 100MHz, 150MHz, and 300MHz. This silicon based approach provides excellent frequency stability and reliability. The 843441 features down and center spread spectrum (SSC) clocking techniques.

Features

  • Designed for use in SAS, SAS-2, and SATA systems

  • One differential 3.3V LVPECL output
  • Crystal oscillator interface designed for 25MHz (CL = 18pF) frequency
  • External fundamental crystal frequency ensures high reliability and low aging
  • Selectable output frequencies: 75MHz, 100MHz, 150MHz, 300MHz
  • Output frequency is tunable with external capacitors
  • RMS phase jitter: 1.33ps (typical)
  • 3.3V operating supply
  • 0°C to 70°C ambient operating temperature
  • Industrial temperature available upon request
  • Available in lead-free (RoHS 6) package
