General Purpose Clock Generators

The Silicon Labs differential clock generators provide any rate, any output frequency synthesis enabling a single device to replace multiple crystal oscillators and fixed-frequency clock generators. Any combination of 4 output frequencies can be generated with exactly 0 ppm error. Independent signal format and VDDO options provide integrated level translation, supporting LVPECL/LVDS/HCSL/LVCMOS clock generation up to 712.5 MHz with sub 1 ps RMS phase jitter.

Features

  • Low-power MultiSynth™ technology enables independent, any-frequency synthesis on four differential output drivers
  • Exact clock synthesis (0ppm error)
  • Crystal or clock input
  • Low phase jitter: 0.7 ps RMS typ
  • Independent output voltage per driver: 1.5, 1.8, 2.5, or 3.3 V
  • Independent core supply voltage: 1.8, 2.5, or 3.3 V
  • 4x4 mm, 24-QFN
  • Low power: 45 mA core supply
  • Industrial temperature range: –40 to +85 °C
