The QTCC578 Series of ultra-miniature crystal oscillators are designed to meet the demand in high-performance, low-voltage applications with an exceptional phase noise floor of -155 dBc/Hz. The QTCC578 oscillators are offered with supply voltages of 3.3 Vdc and 2.5 Vdc. They are built using a miniature strip AT quartz crystal in a low-profile ceramic (5x7x1.5 mm) hermetically sealed package with gold plated contact pads.
The QTCC578 series are LVDS logic differential output crystal oscillators. Models are available with frequency set to between 
100.000 MHz and 250.000 MHz, with temperature range/frequency stability selectable from ±25 ppm at -40 to +85°C to ±100 ppm at -55° to +125°C.
“This QTCC Series answers the demand for low phase noise in a number of commercial applications like fiber channel, telecom, SONET, Ethernet/SynchE and microprocessor clock,” said Scott Sentz, Q-Tech’s Director of Sales and Marketing. “This compact, reliable device is also effective in Mil/Aero applications, such as navigation, avionics and COTS.”
QTCC578 Series oscillators are ECCN: EAR99-classified, lead-free and RoHS compliant. Military screening per MIL-PRF-55310 is also available. They are available now with a delivery time of ~8 weeks (w/o optional MIL-PRF-55310 screening). Many standard frequencies are in stock. Pricing is dependent on package, frequency and screening level.
