Crystek achieves phase noise benchmark of -168 dBc/Hz with CCHD-950 HCMOS clock oscillator development

Crystek Corporation’s Ultra-Low Phase Noise CCHD-950 Series HCMOS Clock Oscillator pushes the phase noise performance benchmark with a -168 dBc/Hz noise floor (100 MHz model). The CCHD-950 generates frequencies between 45 MHz and 130 MHz, with 50 MHz, 80 MHz, 100 MHz and 130 MHz offered as standard.  A high-Q crystal and 3rd overtone technology provide the ultra-low phase noise and low-jitter performance, making the CCHD-950 very useful in synthetic instrumentation such as VXI/PXI.

Generating no sub-harmonics, the CCHD-950 requires an input supply voltage of 3.3 Vdc consuming 15 mA of current.  This high performance oscillator is available in an FR5 9×14 mm SMD package. An extended temperature operating range of -40°C to +85°C is also available. Applications include high definition TV, avionics, low phase signal sources, and test & measurement.
