【New Product】Developed an industry-leading VCXO with ultra-low phase noise and jitter
Kyushu Dentsu Co., Ltd. (KDK) has developed a surface-mount VCXO featuring ultra-low phase noise and ultra-low phase jitter. By combining our crystal design expertise cultivated over many years with proprietary oscillator circuit design, this VCXO achieves an industry-leading phase jitter performance of 18 fs typ. (12 kHz to 20 MHz). In next-generation communications and high-speed data transmission applications, increasingly lower jitter performance is required to improve signal quality. This product is a high-performance VCXO designed to meet these advanced market demands. The currently supported frequency is 122.880 MHz. For other frequencies or custom specifications, please feel free to contact our sales team.
