High-Frequency, Wide Temperature Range and Tight-Stability Crystal Oscillators for Wi-Fi 6 Applications

With the implementation of 5G communications, the need for a higher speed Wi-Fi has become clear. This is why the adoption of Wi-Fi 6, also known as 802.11ax, is accelerating. Wi-Fi 6 brings all of the advantages of 5G, higher speeds, lower latency and increased device density, to more applications. In addition, today’s Wi-Fi Devices are becoming smaller and may be located indoors or outdoors. Due to the reduced sizes and uncontrolled environments many applications are finding that 95 or 105°C operating temperatures are common. To support these issues Wi-Fi 6 needs high stability frequency sources that are engineered to operate in these conditions to ensure data transmission efficiency.

Taitien provides a complete range of products which have been engineered to meet the higher frequency and higher stability challenges of Wi-Fi 6. Taitien’s OX-A and OY-A Types are capable of achieving tight frequency stability of ±10 ppm over -40 to 105°C for Wi-Fi 6’s lower frequencies such as 38.4 and 48MHz. Moreover, Taitien’s PY-U and PZ-U Types satisfy the frequency stability requirement of ±20 ppm over -40 to 105°C for higher frequencies such as 76.8 and 96MHz.
