New ultra-low jitter clock oscillator for defence & aerospace applications

IQD’s new STXO series of surface mount clock oscillators has been designed with an ultra-low integrated RMS phase jitter of 256fs at 2.5V and RMS period jitter of 1.4ps over 10,000 cycles. With a phase noise level of -138dBc/Hz @ 1kHz and -163dBc/Hz at the noise floor, this new series is ideal for defense & aerospace applications such as smart munitions, guidance & navigation and communication systems; although the devices can also be used in demanding industrial applications.
