Product Overview
The 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 LANs, mobile phones, printers, and flat TVs. Featuring a 5.0 x 3.2 x 1.3mm ceramic package, this oscillator offers Tri-state function and is suitable for RoHS reflow profiles. Its seam-sealed ceramic package ensures high reliability, and it is hermetically sealed, making it not moisture sensitive (MSL = N/A). The product supports quick turn delivery with less than 5 days for small quantities.
