Crystal Oscillators for Optical Modules

Key Clocking Requirements for Optical Modules

Ultra-Low Phase Jitter
- 1.6T optical transceivers require integrated phase jitter of <64 fs (typically 35 fs) to guarantee signal integrity.
- Single-lane 400G architectures demand exceptionally low jitter.
High-Frequency & High-Precision

· Requires high-frequency differential crystal oscillators at 156.25 MHz, 312.5 MHz, and 625 MHz.
· Initial frequency tolerance of ±20 ppm.
· Ultra-low aging rate of ±3 ppm/year.
Miniaturized Packaging

Package sizes are evolving from traditional 7×5 mm to ultra-miniature 2016 and 2520 footprints.
Wide-Temperature Stability

Must support a wide operating temperature range of -40°C to 105°C, particularly for demanding outdoor deployments.
