Frequency control specialist Euroquartz has launched a new range of switchable crystal oscillators offering users the ability to provide four different frequencies.
The new QuikXO HC_JF series oscillators are available in frequencies from 15MHz to 2,100MHz with a choice of outputs, including LVCMOS (up to 250MHz), LVPECL, LVDS and CML differential. High current steering logic (HCSL) differential outputs are available for frequencies up to 700MHz. Integrated phase jitter performance of 150fs maximum makes these crystal oscillators particularly suitable for high-frequency applications.
QuikXO HC-JF series crystal oscillators are available at low cost and can be delivered in days for prototypes with a choice of supply voltages – 1.8V, 2.5V or 3.3V – across the range, with the exception of LVPECL at only 2.5V and 3.3V. Customers can select any four frequencies in the range and the oscillator can switch to each as required, useful in frequency bus distribution applications on multi-processor boards where several frequencies are required for the different processors. The four chosen frequencies can all be synchronised from the single crystal oscillator instead of trying to sequence multiple clocks to achieve switching in of the various processors.
Frequency selection is made using two logic control pads, FS0 and FS1, to provide the four user selectable frequencies with frequency select timing of 2.5ms maximum. Frequency stability specifications of ±25ppm, ±50ppm and ±100ppm over both commercial (-10°C to 70°C) and industrial (-40°C to 85°C) temperature ranges are available as standard.
Other specifications include maximum ageing of ±3ppm in the first year, duty cycle of 50% ±5%, rise times of 0.35ns maximum and current consumption from 62mA to 99mA typical depending on output logic selected. Additional features include a start-up time of 5ms typical, 10ms maximum and output enable / disable functions.
RoHS compliant, the new QuikXO HC-JF crystal oscillators are housed in industry-standard 8-pad, 7mm x 5mm surface mount packages capable of withstanding 260°C for ten seconds, twice. Storage temperature range is -55°C to 155°C.
