Integrated Device Technology, Inc. (IDT) entered the all-silicon oscillator market Thursday (April 29), with a line of CMOS oscillators that obsolete the ubiquitous quartz crystal that maintains a time base in most electronic devices today, but without having to resort to micro-electro-mechanical systems (MEMS).

IDT's MM8102 and MM8202 offer frequency accuracies of better than 300ppm and operate a frequencies up to 133MHz. By offering both packaged and bare die, IDT claims its oscillators can eliminate the need for bulky quartz crystals in applications where space is at a premium, such as SIM cards, USB Flash drives and other serial wireline interface applications including S-ATA, PCIe, USB 2.0 and USB 3.0.

Both parts consume about 2 milliAmps at 1.8V, or less than 1 microAmp in standby mode. Unlike MEMS devices, the parts are immune to shock and vibration, according to IDT (San Jose, Calif.).
