VCMOs set new benchmarks with jitters of less than 1-ps
Both the SiT3808, which is specified for the frequency range from 1 MHz to 80 MHz, as well as the SiT3809 (frequency range: 80 MHz to 220 MHz) impress design engineers with its high frequency stability of up to ±1 ppm and 6 decimal places of frequency accuracy. The excellent pull range linearity significantly contributes to minimising variations of the application PLL. Furthermore, possible EMI distortions may be reduced very easily by using the programmable drive level of the devices.
Fully compatible with existing quartz-based VCXO solutions the MEMS VCOs (VCMOs) are available for the commercial temperature range from -20 to +70°C as well as for the extended industrial temperature range from -40 to +85°C. The members of the SiT380X family are available in 3225 packages with 4 pins as well as in 6-pin 7050 packages. The devices operate from a 1.8 V or 2.5…3.3 V power supply.
Due to the individual programmability of several parameters like frequency, stability, operating voltage, pull range and drive level, first customer-specific samples will mostly be available within 48 to 72 hours. The lead time for production quantities is about three weeks.
