Low EMI Oscillators in Miniature Surface Mount Package

Frequency control products specialist, Euroquartz has added a new series of low EMI oscillators to its EQHM family offering a low cost solution to expensive EMI problems.

(PRWEB) January 31, 2006 -- Frequency control products specialist, Euroquartz has added a new series of low EMI oscillators to its EQHM family offering a low cost solution to expensive EMI problems.

The new EQHM53 series oscillators are housed in a 5 x 3.2mm SMD package and offer up to -15dBc EMI reduction. Operating from a 3.3V supply, EQHM53 series oscillators are available covering a broad frequency range from 6 to 160MHz and are drop-in replacements for standard 5 x 3.2mm SMD packaged devices.

EQHM series oscillators reduce EMI radiation in electronic systems at its main source, namely the clock oscillator itself. The low EMI oscillators use spread spectrum technology (SST) whereby the output frequency is modulated by a low frequency carrier spreading the peak energy of the output frequency and its harmonics over a wider bandwidth.

By suppressing EMI at its source, Euroquartz's EQHM53 series oscillators eliminate the need for many expensive EMI protection aids such as PCB groundplanes, metal shielding, ferrite beads, RF gaskets and EMI filters.

Specifications include "high" output voltage of 2.4V minimum, "low" output voltage of 0.4V maximum, output load of 10LSTTL gates or 15pF and operating temperature from -40 to +85 deg C for industrial versions and 0 to 70 deg C for commercial types.

EQHM53 series oscillators deliver duty cycle of 45/55, rise/fall times of 5ns maximum (1.5ns typical), current consumption of 15 to 45mA (frequency dependent) and peak frequency reduction of 10 to 16dB for 3rd to 19th odd harmonics. Pin 1 options include modulation on/off, tri-state for all outputs and power down. Ageing is ±5ppm/year maximum while standard jitter is typically 250ps.

Available on tape and reel, Euroquartz's new EQHM53 series SST oscillators provide a drop-in replacement and low cost solution to expensive EMI problems.

With annual turnover of £3.5million and a current growth rate of 12.5% per annum, Euroquartz group provides major OEMs with a global manufacturing and supply facility for all types of quartz crystals, oscillators, filters and frequency control products.
