wurth iqd iqxo 923 lidIQD 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 ±5 ppm over the full industrial operating temperature range of -40 to 85 °C.





Available in either a voltage of 1.8 V (IQXO-923-18) or 3.3 V (IQXO-923-33) this new clock oscillator is housed in an hermetically sealed 3.2 × 2.5 mm ceramic package with a height of 1.1 mm.
Frequencies can be specified in the range 10 MHz to 160 MHz and offer a start-up time of 5 ms. With a phase jitter (12 kHz to 20 MHz) of 0.4 ps typical and a phase noise of -99 dBc/Hz at 100 Hz and -144 dBc/Hz at 10 kHz 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.
