New Crystals Operating over Extended -55°C to +125°C Temperature Range



Low-cost, resistance weld crystals maintain tight tolerances and stabilities

Fox has enhanced its HC49 line of low-cost resistance weld crystals with two versions that maintain stability and tolerances across an extended temperature range of -55°C to +125°C.
 
The SMD HC49SDLF and thru-hole HC49SLF offer frequencies from 3.2 MHz to 80 MHz in the same compact 14 mm x 5 mm package with maximum heights of 4.5 mm and 3.6 mm, respectively. 

The large temperature and frequency ranges, as well as the compact, robust housing make the new crystals ideal for a variety of harsh environments including mobile devices and exterior telecommunication installations.

XPRESSO Oscillator 3.2 x 2.5mm 3.3V with 0.75 MHz to 250MHz frequency

The Fox XPRESSO Crystal Oscillator is a breakthrough in configurable Frequency- 0.75 MHz to 250MHz Control Solutions. XPRESSO HCMOS 3.2 x 2.5mm 3.3V Oscillator utilizes a family of proprietary ASICs, designed and developed by Fox Electronics, with a key focus on noise reduction technologies.
The 3rd order Delta Sigma Modulator reduces noise to the levels that are comparable to traditional Bulk Quartz and SAW oscillators. The ASICs family has ability to select the output type, input voltages, and temperature performance features.
With the XPRESS lead-time, low cost, low noise, wide frequency range, excellent ambient performance, XpressO is an excellent choice over the conventional technologies. Finished XPRESSO parts are 100% final tested.
