Product Description
Product Overview
The ClearClock AK7 series is an ultra-low jitter, 7.0 x 5.0mm XO oscillator designed for high-performance applications. It offers a frequency range from 100MHz to 220MHz with exceptional stability options of 20ppm and 25ppm over a -40C to +85C temperature range. Featuring lowest-in-class power consumption, this oscillator supports LVPECL, LVDS, and HCSL differential output types and a wide range of supply voltages (3.3V, 2.5V, 1.8V). Its ultra-low jitter of 75 fs typ RMS makes it ideal for demanding applications in networking, communications, datacenter, and test & measurement sectors.
