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.
