KoT-cut OPAW Crystal Unit
KCRO-04
3.2 × 2.5 (mm: L × W)
Low phase noise／Low phase jitter／High precision／100 MHz to 1000 MHz
- OPAW oscillator using patented new cut angle 'KoT cut'
- Output frequency: 100MHz ~ 1GHz
- Achieves higher frequency stability over a wide temperature range than AT cut
- Supports LVDS or LVPECL output
- RMS phase jitter: 20 femtoseconds (typ. / SPXO)
- Applications: Communication equipment, supercomputers, measuring instruments
