Product Overview
The Abracon ASSFLP Series is a programmable spread spectrum, low EMI clock oscillator designed for a wide range of electronic applications including laptop computers, PDAs, LCDs, digital cameras, wireless LAN devices, mobile phones, printers, and flat TVs. Featuring a 5.0 x 3.2 x 1.3mm ceramic package and tri-state function, this oscillator is suitable for RoHS reflow profiles and offers high reliability due to its seam-sealed ceramic construction. It provides EMI reduction across the entire frequency spectrum and is available in 2.5V or 3.3Vdc supply voltages.
