KoT cut OPAW

KoT cut OPAW

KoT cut OPAW is River Eletec’s proprietary crystal technology platform designed for advanced frequency control and ultra-low phase noise clock generation. By combining the original KoT cut crystal structure with OPAW (Orthogonal Plate Acoustic Wave) vibration, this next-generation architecture enables ultra-high-frequency fundamental-mode oscillation together with excellent temperature stability in a compact package. By thoroughly suppressing unwanted resonances (spurious modes), it delivers a clean signal spectrum and ultimate precision.
This innovative technology is offered in two powerful formats to meet the exact needs of advanced hardware engineers. When deployed as a crystal unit paired with a customer’s IC, it fundamentally elevates baseline communication quality. More importantly, when integrated with a custom-designed, optimized IC to form a high-performance crystal oscillator, it significantly reduces phase jitter in high-speed serial communication approaching the GHz range. This plug-and-play solution eliminates the need for complex circuit matching, delivering an overwhelmingly low noise floor right out of the box.
These devices provide the optimal timing solution for highly demanding environments—from network analyzers and aerospace to AI data center optical transceivers supporting 1.6 Tbps-class data transmission with flawless signal integrity.
