In recent years, there has been a growing need for further low-jitter reference clocks to improve communication performance in high-speed mobile communications such as 5G and LTE, and in serial communications such as SONET\/SDH, 10Gbit\/Ethernet, SATA, and PCI-Express, both at higher speeds and at larger capacities.<\/p>\n

If the jitter is large, it may interfere with adjacent signals and cause noise and communication performance deterioration.<\/p>\n

To meet these needs, in June 2018 we released a LVDS differential-output crystal oscillator with phase jitter reduced to 57fs (at 156. 25MHz). After that, we developed a high-frequency fundamental-wave crystal unit using photolithography technology and a low-noise differential-oscilla tion IC. As a result, we succeeded in developing a LVDS, PECL differential-output crystal oscillator with lower noise than before. LVDS differential output crystal oscillator has a phase jitter of 47fs typ. (*1) which is a 10fs typ. reduction compared to the conventional product.<\/p>\n

In the future, we will use this technology to gradually expand our lineup of products to other differential output methods, HCSL output, to meet the needs of our customers.<\/p>\n
