High stability oscillators ready to ship

Hong Kong X’tals’ high frequency crystal oscillators are designed to ensure high stability and low noise. The company states this is made possible thanks to a differential output and low-phase jitter. The manufacturer is addressing growing demand for low-cost, low-jitter timing references in telecommunications applications such as LTE/5G, PCI-e Express and 10-Gbit Ethernet.

The oscillators with LVDS/LVPECL/HCSL output are available with, for example, 100.00, 100.0025, 125.00, 148.3516 or 148.50MHz and all frequently used frequencies. The LVPECL variant operates at 3.3V. General frequency stability is ±50ppm.

Operating temperature range is -40 to 85°C or 125°C—crucial for applications in industrial environments. Measuring 3.2 by 2.5mm or 2.5 by 2.0mm, the design is considered very compact.
