Ecliptek Corporation has announced the expansion of its EMS MEMS spread spectrum low EMI output surface mount oscillator, the EMS4 series. The EMS4, in a miniature 2.0mm x 2.5mm package, reduces EMI at the clock source instead of locations later down the clock stream, potentially eliminating the use of supplemental shielding enclosures and/or filtering components.
This greatly reduces system costs and improves overall EMI performance. Applications for the EMS series include set-top boxes, medical equipment, scanners, printers, LCD displays, and communications equipment.

Standard specifications for the EMS4 series include a frequency range of 1MHz to 175MHz; 1.8V, 2.5V or 3.3V supply voltage; ±50ppm or ±100ppm frequency stability; LVCMOS single ended output; programmable spread percentages of ±0.25%, ±0.50% and ±1.00% center spread and -0.5%, -1.0%, -2.0% down spread; spread spectrum enable/disable function; and tri-state or power down options for a high impedance output.
