XpressO oscillators fromFox Electronics are optimised specifically for fibre channel configurations. As with allmodels in the new 3.3V XpressO line, the fibre channel oscillators are off-the-shelf, pre-configured to application-specific requirements in an industry standard 7.0 by 5.0mmpackage.
The application specific XpressO line combines Fox's patented
technologywith specific characteristics for fibre channel applications, butwithout thewait associatedwith customproducts. XpressO technology boasts fast delivery of lowjitter, small package size andmultiple frequency and output options. The devices utilise a family of ASICswith a focus on noise reduction.
Fibre channel specific XO oscillators offer a frequency stability
of ±50ppmwith tighter stabilities available upon request and are available in 106.25, 159.375and 212.50MHzmodels.
Pricing for a 106.25MHz HCMOS oscillator is $0.78 in quantities
of 50,000. As with all XpressO products, samples are available overnight, small quantities in two to three days and up to 20,000 in one to two weeks.

Low voltages, low profiles
Euroquartz has released four new ranges of low voltage crystal oscillators inminiature surfacemount packages. The new XO22, XO32, XO53 and XO91 series offer supply voltages fromfive down to 1.0V enabling current consumption as low as 2.0mA andmaking the oscillators ideal for use in battery powered applications.
XO22 series oscillators are packaged in a low-profile 2.5 by 2.0 by
0.9mmsurfacemount package and offer frequency range from0.5 to 75MHz. XO32 devices are housed in a 3.2 by 2.5 by 0.95mmSMD packagewith frequency range from0.5 to 54MHz. XO53 series clock oscillators are 5.0 by 3.2mmsurfacemount devices offering 1.0 to 125MHz and XO91 series clock oscillators are housed in 7.0 by 5.0 by 1.4mmhermetically sealed packages offering 312.5kHz up to 160MHz.
All four ranges are available with supply voltage options of 1.0, 1.2,
1.8, 2.5, 3.3 or 5.0V and all offer HCMOS/LSTTL output logic. Tristate function is standard on all ranges.
