December 3, 2008: Ecliptek Corp., a supplier of frequency control products, has introduced its new EMS4 series of MEMS-based spread spectrum programmable clock oscillators. These silicon resonator based oscillator devices greatly reduce cost and lead time as compared to similar quartz-based oscillator products.

The EMS4, in a miniature 2.0mm × 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.

Using a proprietary ASIC and state-of-the-art programming techniques, Ecliptek is able to program and deliver EMS4 series products in as little as seven days ARO. Prices start at $2.71 EA in 1000 piece quantities on tape and reel.

Standard specifications for the EMS4 series include a frequency range of 1MHz-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 high impedance output.
