Versatile crystal clock generator - 2nd Gen

The CG50LP is CISSOID’s 2nd generation clock generator IC. It combines the unrivalled robustness of its predecessor device CG50, while bringing additional features, lower pin count and ~40% current consumption reduction (compared to CG50). 

The CG50LP is a high-temperature crystal clock Generator integrated circuit that features a built-in frequency divider selectable from 1 to 512, an enable/disable control signal and an external clock input.  Its output driver capability is programmable (8/16mA) as well as the crystal driver strength. Using an external crystal, it brings reliable precision performance throughout the -55 to +225°C temperature range, as well as unrivalled lifetime at any temperature within this range.

Typical performances

  • Operating temperature (Tj): -55°C to 225°C
  • Power supply: 3.3V +/-5% to 5V +/10%
  • Frequency range: DC to 50MHz
  • 3-states output buffer
  • Programme output buffer: 8/16mA
  • Programmable output frequency divider: 1:1 to 1:512
  • Programmable crystal driver strength
  • Stand-by mode
  • Built-in passive components



  • Clock buffer & clock generation in downhole tools, aerospace, defense and HiRel applications.
