TAITIEN Electronics, a leading provider of frequency control solutions, has introduced a new line of high frequency voltage-control crystal oscillator (VCXOs) with low phase jitter, capable of achieving frequencies up to 800MHz. Leveraging TAITIEN’s long history of making high-performance VCXOs and expertise in end-to-end fabrication of high-frequency quartz crystal oscillators, the new VCXO is capable of providing high frequency with phase jitter reaching 40 fs (femtoseconds) @491.52MHz in both 7x5mm and 9x14mm SMD packages.
Taking advantage of Taitien’s proprietary Inverted Mesa technology as well as low-noise analog multiplier circuits, the VT and VK series of VCXOs can achieve very high frequencies for high-speed communication networks with excellent phase noise and large frequency pulling up to ±150ppm with minimal frequency multiplication. At the supply voltage of 3.3V, the VCXOs operate over temperature range from -40 to 85oC and can reach frequency stability as low as +/-25ppm. The VCXOs are available in both LVPECL and LVDS output waveforms. These features make the VT and VK series optimal solutions in wide range of applications such frequency synthesizer, jitter-attenuating and clock recovery circuits.
With increasing demand for high-speed data communication networks, high-frequency VCXOs with low phase noise are becoming critical components enabling developments such as 4G cellular network, Remote Radio Head (RRH) for distributed base stations, and microwave backhaul equipments. Taitien’s VT and VK series are capable of delivering very low jitter performance at high frequencies to improve signal quality required for these applications.
