The 844201-45 is a PCI Express®TM Clock Generator. The 844201-45 can synthesize 100MHz or 125MHz reference clock frequencies with a 25MHz crystal. The 844201-45 has excellent phase jitter performance and is packaged in a small 8-pin TSSOP, making it ideal for use in systems with limited board space.

Features

  • One differential LVDS output
  • Crystal oscillator interface designed for 18pF, 25MHz parallel resonant crystal
  • VCO range: 490MHz - 680MHz
  • RMS phase jitter at 100MHz (12kHz - 20MHz): 0.792ps (typical)
  • RMS phase jitter at 125MHz (12kHz - 20MHz): 0.773ps (typical)
  • Full 3.3V output supply mode
  • PCI Express® (2.5 Gb/s) and Gen 2 (5 Gb/S) jitter compliant
  • 0°C to 70°C ambient operating temperature
  • Available in lead-free (RoHS 6) package
