CTS crystal oscillators are available in a variety of hermetically sealed ceramic package sizes. The oscillator designs are fully RoHS compliant and lead-free. Product highlights include stable output over the operating temperature range, excellent phase noise and jitter characteristics, and improved shock performance due to the smaller package sizes.  Standard output types such as HCMOS, LVPECL and LVDS are available. CTS is beginning to incorporate a DLD package design for the clock oscillator product series. The DLD package allows for measurement of the crystal parameters in the finished oscillator, helping to identify marginal units before leaving the factory.
