COR PORATI ON
LOW PROFILE 5 x 7mm MINIATURE SMD CRYSTAL OSCILLATORS
Description
Q-Tech’s surface-mount QCC570 LVPECL and LVDS oscillators
consist of a 2.5Vdc and 3.3Vdc differential PECL or LVDS output
oscillator IC and a miniature strip AT quartz crystal built in a low
profile ceramic package with gold plated contact pads.
