Euroquartz launches new UK manufactured range of high frequency ultra-low jitter voltage-controlled crystal oscillators

Frequency control specialist, Euroquartz has launched a new range of UK manufactured surface mount voltage-controlled crystal oscillators (VCXO) offering high frequency outputs with ultra-low phase jitter performance. The new EG_JF series offers frequencies from 15 to 2100MHz for CMOS, LVPECL, LVDS and CML differential outputs and 15 to 700MHz for HCSL differential outputs. A major advantage of these components is that they are manufactured in Euroquartz’s cleanroom facility in southwest UK and are free of ITAR restrictions.

The new EG_JF series oscillators are ideal for use in a wide range of applications where ultra-low phase jitter is a prime requirement. Typical RMS phase jitter performance ranges from as low as 151fs at 644.530MHz up to 163fs at 2000MHz.

The components are housed in a standard format 8-pad 7x5mm SMD ceramic package with hermetically sealed metal lid. Power supply voltage options are 1.8V ±5% (except LVPECL types), 2.5V ±10% and 3.5V ±10% (all types) with current consumption ranging from 70 to 120mA maximum depending on frequency and logic type. Standard temperature stability specification options available are ±25, ±50 and ±100ppm over commercial (-10 to +70°C) and industrial (-40 to +85°C) temperature ranges with tighter options available upon request.

Additional specifications include rise/fall time of 5ns maximum for CMOS types, 0.4ns maximum for all others (20% to 80% waveform), duty cycle of 50% ±5% for all types (except 1.8V CMOS at ±10%) and output enable/disable function as standard. Ageing is ±3ppm maximum for first year, ±2ppm maximum thereafter. Solder profile is 260°C maximum for 10 seconds, twice.

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

Euroquartz is an independent UK-based manufacturer and supplier of quartz crystals, oscillators, filters and frequency-related products to the electronics manufacturing industry worldwide. The company is AS9100 registered and designs and manufactures a comprehensive range of frequency control components for a wide range of customers including major OEMs covering a broad spectrum of applications including defence and aerospace, communications, general electronics, computing, control systems and petrochemical among many others.
