MEMS oscillators available for industrial temperature ranges

MEMS oscillator's frequency instability at extreme temperatures has been one of the reasons that crystal oscillators still have a foothold in many industrial applications. That might change now that Discera has expanded its PureSilicon product offering to include industrial temperature ranges (-40 to +85 C) with +/- 50ppm and +/- 25ppm frequency stability.

According to Discera, their PureSilicon MEMS oscillators are pin-compatible with popular crystal oscillators and have low operating current specs (3mA typ. at 40MHz), while consuming 1uA in standby mode. MEMS oscillators are more impervious to shock, vibration and fractures than crystal parts.

MEMS oscillators now cost 20% less than comparable crystal oscillators, according to Discera.

PureSilicon industrial temperature range oscillator samples are currently available with production volumes available in 3Q of this year. PureSilicon oscillators are available in 2.5x2.0mm, 3.2x2.5mm, 5.0x3.2mm and 7.0x5.0mm plastic packages. With +/-25ppm frequency stability over the industrial temperature range, the 1.8v, DSC1018 device in a 5.0 x 3.2mm package is priced at $1.10 /ea. in 1,000 piece quantities.
