Bala Cynwyd, Pa. - Micro Oscillator, Inc. has introduced a new clock oscillator, the MOI-2000, that can replace ceramic resonators and crystal oscillators in microcontroller-based systems that don't require precise accuracy.
The MOI-2000, which is a CMOS integrated circuit, can operate at +/-0.5% total frequency accuracy over the temperature and voltage range without using ceramic resonators, quartz crystals or other external components for frequency determination.
Unlike ceramic resonators or crystal oscillators that rely on mechanical vibration for frequency generation, the MOI-2000 generates its frequency through an integrated circuit with no mechanical vibration, said the company. Another benefit is the MOI-2000 can be integrated into other silicon.
The patented temperature compensated oscillator offers a frequency range from 2 MHz to 20 MHz. The total tolerance is +/-0.5% over a standard temperature range of 0 degrees C to 70 degrees C. The total tolerance is inclusive of initial frequency tolerance, tolerance over temperature and voltage, and long-term tolerance. The MOI-2000 also operates over an industrial temperature range of negative 40 degrees C to 85 degrees C with a total tolerance of +/-1.0% and over an automotive temperature range of negative 40 degrees C to 150 degrees C with a total tolerance of +/-1.5%.
The MOI-2000 operates at 5 volts or 3.3 volts. The current consumption is 1.6 milliamps for the 5-volt device and 0.7 milliamps for the 3.3-volt device. The devices are available in MSOP-8 and SOP-8 packages.
Pricing for the MOI-2000 starts at $0.45 in quantities of 10,000. Samples are available.
