MEMS oscillators offer 600-fs phase jitter

Targeting telecom, networking, storage and wireless applications, the SiT8208 and SiT8209 MEMS-based programmable oscillators operate from 1 to 80 MHz and 80 to 220 MHz, respectively. Both devices offer a phase jitter of 600 fs measured from 12 kHz to 20 MHz and achieve a stability of 10 ppm over the industrial temperature range, which is two times better than quartz-based solutions.

The SiT820X family comes with an array of programmable features that enable over 200 part numbers, every one of which can be a drop-in replacement for existing quartz, SAW or overtone oscillators. Operating voltage is from 1.8 V and 2.5 to 3.3 V, and temperature range is from –40° to 85°C and from –20° to 70°C. (SiT8208 in 2520 package, 50 ppm, $0.65 ea/10,000 — samples available June.)
