Ultra-tight stability clock oscillator delivers ±5ppm stability

IQD IQD IQXO-923 series of ultra-low frequency stability HCMOS based clock oscillators is available with a frequency stability of only ±5ppm over the full industrial operating temperature range of -40 to 85C. Available in either a voltage of 1.8V (IQXO-923-18) or 3.3V (IQXO-923-33) device is housed in an hermetically sealed 3.2 x 2.5mm ceramic package with a height of 1.1mm. Frequencies can be specified in the range 10MHz to 160MHz and provide 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 suitable for use in designs where a clock oscillator can be used in place of an expensive TCXO.
