Ultra-Tight Stability Clock Oscillator

Posted: 30th April 2019

Ultra-Tight Stability Clock OscillatorIQD has launched a new range of ultra-low frequency stability HCMOS based clock oscillators. The IQXO-923 series is available with a frequency stability of only ±5ppm over the full industrial operating temperature range of -40 to 85 degrees C. Available in either a voltage of 1.8V (IQXO-923-18) or 3.3V (IQXO-923-33) this new clock oscillator is housed in an hermetically sealed 3.2 x 2.5 mm ceramic package with a height of 1.1mm.

Frequencies can be specified in the range 10MHz to 160MHz and offer a start-up time of 5ms. With a phase jitter (12kHz to 20MHz) of 0.4ps typical and a phase noise of -99dBc/Hz at 100Hz and -144dBc/Hz at 10kHz these oscillators are ideal for use in designs where a clock oscillator can be used in place of an expensive TCXO. Applications include Ethernet, networking, smart meters, SONET, test & measurement, WLAN and Wi-Fi.       

The IQXO-923 includes an enable and disable function on pin 1 as standard and packaging options are either ‘Tape and Reel’ or ‘Cut Tape’. Further details are available on IQD’s website at www.iqdfrequencyproducts.com or for further advice, speak to a member of our Applications Support Team.
