Versatile crystal clock generator

The CG50 is a high-temperature crystal clock Generator integrated circuit. It features a crystal oscillator driver with disable input, an ancillary clock signal input and a programmable divider chain. Using an external crystal, it is intended to provide reliable precision performance throughout the -55 to +225°C temperature range.



CHT-CG50LP is the 2nd generation of our crystal clock generator and is more recent than the CHT-CG50.

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: 8/16/24/32mA
  • Programmable output frequency divider: 1:1 to 1:8
  • Programmable crystal driver strength
  • Stand-by mode
  • Built-in passive components
  • Package: ceramic DIL24



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