PRESS RELEASE (No. 464)
May 2017 FOR IMMEDIATE RELEASE
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. Designed around a hermetically sealed high-shock crystal and a CMOS compatible integrated circuit, environmental performance is also good with the STXO able to survive shock levels of up to 20,000G and vibration levels of 20G at 10-2000Hz swept sine in accordance with MIL-STD-202G.
Housed in an industry standard 3.2 x 2.5mm 4-pad ceramic package with a metal lid, the new STXO series uses minor temperature compensation to achieve tight frequency stability of ±10ppm over an operating temperature range of -40 to +85 degrees C and ±20ppm over the full military operating temperature range of -55 to +125 degrees C.
Frequencies between 10MHz and 55MHz can be specified along with a choice of 2.5V and 3.3V supply voltages; current consumption is 3mA with a 15pF CMOS drive capability.
Variants are also available which incorporate enable/disable and tri-state control. In keeping with its military capability the range can be specified with a number of termination finishes including tin/lead in applications where using a device that is RoHS compliant would cause approval issues. However RoHS compliant finishes are also available for less sensitive applications. Duty cycle is 45% min and 55% max with a start-up time of 5ms max and a rise and fall time of 5ns max. Packaging options include tray pack or tape and reel. Further information is available at www.iqdfrequencyproducts.com/search/?q=stxo
