Product Overview
The ASSVP Series is a programmable spread spectrum, low EMI clock oscillator housed in a compact 7.0 x 5.0 x 1.4mm ceramic package. Designed for applications requiring reduced electromagnetic interference, this oscillator offers a frequency range from 13.000MHz to 160.0MHz and is available with supply voltages of 2.5V or 3.3Vdc. Key features include a tri-state function for control and a seam-sealed ceramic package ensuring high reliability. It is suitable for RoHS reflow profiles and is ideal for use in consumer electronics such as laptop computers, PDAs, LCDs, digital cameras, wireless LAN devices, mobile phones, printers, and flat TVs. The product benefits from quick-turn delivery for small quantities.
