In today’s explosive internet traffic growth driven by data intensive applications such as video file sharing and cloud computing, the need to increase the connection bandwidth to accommodate the data demand is becoming one of the priorities of major telecommunication carriers. As a result, the high-speed communication infrastructure rollout 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 10/40/100Gb Ethernet, FTTH, SONET, and clock recovery circuits. Taitien products with inverted mesa blanks are capable of achieving phase noise of as low as -143 dBc/Hz at 10KHz 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. 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.
