In today’s explosive growth in smartphones and handheld electronics which connect to the Internet constantly transmitting and running various applications, more and more computing and data processing is done in large data centers, i.e., in the “cloud”. In order to unlock the vast potential of cloud computing, it is imperative to ensure the data transmission between data centers and terminal devices is fast and smooth. As a result, the high-speed communication infrastructure rollout by major telecommunication service providers is well underway. TAITIEN Electronics, a technology leader in frequency control solutions, has been at the forefront of pushing fabrication technology on quartz resonators to enable high-frequency and low phase noise crystal oscillators to fulfill the performance requirements by high-speed networking and next generation wireless communication systems. Taitien’s proprietary inverted mesa technology utilizes photolithography manufacturing similar to that commonly seen in semiconductor fabrication to produce quartz blanks capable of fundamental resonance of as high as 320MHz which cannot be achieved by the traditional mechanical lapping and polishing techniques
Leveraging the inverted mesa technology, Taitien offers a variety of high-frequency crystal oscillators and VCXOs targeted for applications such as 10G/40G Ethernet switches for data centers, FTTH, jitter attenuating and clock recovery circuits. Taitien products with inverted mesa blanks are capable of achieving phase noise of as low as -143 dBc/Hz at 10K Hz offset and phase jitter of 0.1ps. This performance is far superior to that from clock oscillators using frequency multiplication approach such as PLL to obtain high frequencies. Consequently, Taitien’s low phase noise crystal oscillators can be utilized as clean clock sources for additional frequency synthesis. Currently, Taitien’s inverted mesa blanks are incorporated in the OT and VT product lines in the popular 7x5mm SMD packages with many popular frequencies available, such as 156.25MHz, 155.52MHz and 212.5MHz. The smaller package VCXO and crystal oscillator lines such as the 5×3.2mm VW series also utilizes this technology to meet the increasing need for device miniaturization.
