Ultra-tight stability clock oscillator for use in place of TCXO

It has been announced that IQD 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°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 3.2x2.5mm ceramic package with a height of 1.1mm.

Frequencies can be specified in the range ten to 160MHz and offer a start-up time of five milliseconds. 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 well suited 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 and measurement, WLAN and WiFi.

The IQXO-923 includes an enable and disable function on pin one as standard and packaging options are either ‘Tape and Reel’ or ‘Cut Tape’.
