Ceramic package voltage-controlled crystal oscillators (VCXO) for serial communications offered by Saelig

FAIRPORT, N.Y. – Electronics distributor Saelig Co. Inc. in Fairport, N.Y. is offering the EG-JF series surface-mount voltage-controlled crystal oscillators (VCXO) for applications where ultra-low phase jitter is an essential requirement.

The EG-JF series is from frequency control specialist Euroquartz Ltd in Crewkerne, England. The VCXO devices offer high frequency outputs with ultra-low phase jitter performance, and operate at frequencies from 15 to 2100 MHz for CMOS, LVPECL, LVDS, and CML differential outputs and at 15 to 700 MHz for HCSL differential outputs.

Typical RMS phase jitter performance ranges from as low as 151 fs at 644.530 MHz to 163 fs at 2000 MHz. The oscillators are housed in a standard format 8-pad 7-by-5-millimeter SMD ceramic package with hermetically sealed metal lid.

Power supply voltage options are 1.8 volts plus-or-minus 5 percent (except LVPECL types), 2.5 volts plus-or-minus 10 percent, and 3.5 volts plus-or-minus 10 percent (all types) with current consumption ranging from 70 to 120 milliamps maximum depending on frequency and logic type.

Standard temperature stability specification options available are plus-or-minus 25, plus-or-minus 50, and plus-or-minus 100 ppm over commercial temperatures from -10 to 70 degrees Celsius, and industrial temperatures from -40 to 85 C with tighter options available on request.

Additional specifications include rise/fall time of 5 nanoseconds maximum for CMOS types, 0.4 nanoseconds maximum for all others (20 percent to 80 percent waveform); duty cycle of 50 percent plus-or-minus 5 percent for all types (except 1.8 volts CMOS at plus-or-minus 10 percent); and output enable/disable function as standard. Ageing is plus-or-minus 3 ppm maximum for the first year, and plus-or-minus 2 ppm maximum thereafter.

The Euroquartz EG-JF series VCXOs are for applications such as flat panel displays for consumer TVs; video streaming systems via external cables (e.g. LDI); and high-speed serial communications links such as Serial ATA & FireWire, SONET, xDSL, SDH, set-top box, and Ethernet cards.
