Press Release – QTCC578 Ultra Miniature Low Phase Noise LVDS Clocks

Q-Tech Ultra-Miniature Oscillators Boast Exceptionally Low Phase Noise

QTCC578 Series surface mount oscillators are ideal for a wide range of telecom and avionics applications


Cypress, CA— December 15, 2020—Q-Tech Corporation, the world’s leading supplier of crystal oscillators for space, military, avionics and high-temperature applications, announces the availability of the QTCC578 Series of ultra-miniature crystal oscillators 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 3.3Vdc and 2.5Vdc. They are built using a miniature strip AT quartz crystal in a low-profile ceramic (5mm x 7mm x 1.5mm) hermetically sealed package with gold plated contact pads.
