Sample Shipment Begins for RIVER ELETEC’s Innovative Single-chip Oscillator KCRO-04, Achieving 1GHz Fundamental Oscillation and Future-leading RMS Jitter of 20fs

Sample Shipment Begins for Innovative Single-chip Oscillator "KCRO-04"- Achieving 1GHz fundamental oscillation and future-leading RMS jitter of 20fs.

RIVER ELETEC Corporation (hereinafter referred to as "our company") is proud to announce the market introduction of KCRO-04, a fundamental product essential for accelerating the evolution of high-speed communication and next generation computing. This product is the third in our series of innovative products utilizing our developed KoT cut and OPAW vibrational technology, with sample shipments having commenced in May 2024.

A particularly important note is the high-performance IC, developed independently by our company, which serves as the heart of KCRO-04. This proprietary oscillation IC is custom-designed to extract the performance of the KoT cut oscillator, enabling fundamental oscillation up to 1GHz while suppressing RMS jitter to less than 20fs. This results in unparalleled high-precision performance in the market, showcasing our technical prowess and uniqueness.

Despite its compact size (3.2mm x 2.5mm), KCRO-04 boasts superior performance and achieves the highest level of performance currently available. This outstanding performance allows KCRO-04 to meet the demands for high-precision, stable signals in high-speed communication and next generation computing technologies that push the limits of computational power, establishing a new standard for technological innovation in these fields.

Jitter and phase noise performance (LVDS, 1GHz)

KCRO-04 supports LVDS and LVPECL outputs, offering excellent frequency temperature characteristics through KoT cut. This technology ensures stable operation over a wide temperature range, making it ideal for applications requiring high reliability. In addition, by not using a PLL, it achieves extremely low noise frequency output, significantly improving signal stability and information accuracy, particularly in applications requiring high-speed data transfer and precise calculations.

This revolutionary technology is expected to play a significant role in both communication and computing fields, greatly accelerating their technological evolution. From the construction of high-speed communication networks to high-performance computing in large data centers, and even as a foundation for cutting-edge technologies like artificial intelligence and machine learning, KCRO-04 is expected to find a broad range of applications.

We are committed to further developing KoT cut and OPAW vibration technologies and continuing to explore the future possibilities these technologies open. Through our KCR series of products, including KCRO-04, we will provide our customers with state-of-the-art technology solutions and contribute to the development of the industry. We, RIVER ELETEC, promise to forge a new horizon in future communication and computing together with our customers through this innovative product.
