PORTLAND, Ore. 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.).
Other companies offering all-silicon CMOS oscillators that do not use MEMS include Silicon Laboratories Inc. (Austin, Texas), Mobius Microsystems Inc. (Sunnyvale, Calif.), National Semiconductor Corp. (Santa Clara) and Linear Technology (Milpitas, Calif.). In addition, Silicon Labs is hedging its bets on MEMS, by purchasing MEMS oscillator startup Silicon Clock's earlier this week..
