Product details

27 MHz MEMS oscillator with standby function

The DSC1033BE1-027.0000T is a MEMS-based XO (Standard) oscillator delivering a fixed 27 MHz CMOS output from a 3.3V supply rail. The typical supply current is 3 mA, and the standby (power down) function drops current consumption to 1 µA, making it suitable for battery-operated equipment that spends most of its time in a low-power sleep state.

Surface-mount package and footprint

Housed in a 4-SMD, No Lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm. This industry-standard footprint is compatible with common pick-and-place and reflow processes. The -20°C to +70°C operating temperature range covers commercial and most industrial indoor environments.

Frequently asked questions

Does the DSC1033BE1-027.0000T have a standby (power down) function?

Yes. The standby function (labeled 'Standby (Power Down)') reduces the supply current to 1 µA when the enable pin is de-asserted. This allows the system to power down the oscillator during idle periods and wake quickly without the startup delay of a crystal.
