Euroquartz has introduced a new range of low-EMI oscillators that feature enhanced jitter performance. The new 3EQHM53Y series is suitable for use in a wide range of applications and use spread spectrum (dithered) techniques to reduce EMI emissions from the oscillator by as much as 15 dB. Spread spectrum technology spreads the mode energy over a wider bandwidth while the modulation carrier frequency, operating in the kHz region, makes the process transparent to the oscillator frequency.
These new devices also offer enhanced jitter performance with cycle-to-cycle jitter of ±100 ps. Housed in standard 5 x 3,2 x 1,2 mm surface mount packages, they are a direct drop-in replacement for standard oscillators. Specifications include frequency range from 10 to 160 MHz, choice of four spread types (down spread 1% and 3% and centre spread ±0,5% and ±1,5%), EMI reduction from -9 dBc minimum to -15 dBc minimum depending on spread type, and modulation carrier frequency from 12 kHz minimum to 42 kHz maximum.
Frequency stability characteristics are ±25 ppm, ±50 ppm or ±100 ppm over both commercial (0 to 70°C) and industrial (-40 to +85°C) temperature ranges.
With their low EMI emissions and enhanced jitter performance, the new oscillators are RoHS compliant.
