Stratum 3 TCXOs are used in the networking market. Compared to the consumer grade TCXO with frequency stability ±2 ppm or ±0.5 ppm over temperature (TXC’s 7Q, 7L, 7Z, 8P product series) performance, TXC’s 7P and 7N-series are designed for high stability applications such as base station, small-cell, networking infrastructure and smart grid which need reference clock with ±0.28 ppm or ±0.14 ppm frequency stability over temperature and outstanding short-term and long-term frequency stability performance.
