Product details

AEC-Q100 Grade 1 – under-hood capable

MEMS resonator – shock tolerance and fast start

MEMS oscillators typically withstand higher shock and vibration than quartz, and they start up faster — relevant for automotive ECUs and industrial controllers that cycle power frequently.

Enable/Disable pin – power gating the clock

The 2.25V to 3.6V supply range covers both 2.5V and 3.3V logic rails without an external regulator. This simplifies the power tree in mixed-voltage designs and reduces BOM count.

Package – 6-SMD no-lead, 3.2mm x 2.5mm

Housed in a 6-SMD no-lead package measuring 3.20mm x 2.50mm with a seated height of 0.90mm. The small footprint suits space-constrained PCBs in automotive ECUs, ADAS modules, and industrial sensor nodes.

Frequently asked questions

Is the DSC1121CI2-027.0000 AEC-Q100 qualified?

Yes, the DSC1121CI2-027.0000 carries an AEC-Q100 rating.

Does the DSC1121CI2-027.0000 have an enable/disable function?

Yes, the DSC1121CI2-027.0000 includes an Enable/Disable function. When disabled, the maximum supply current drops from 35 mA to 22 mA.

Can the DSC1121CI2-027.0000 replace a standard quartz oscillator of the same frequency?

Yes, the DSC1121CI2-027.0000 is a drop-in replacement for a 27 MHz quartz oscillator in the same 6-SMD no-lead footprint, provided the supply voltage (2.25V-3.6V) and output type (CMOS) are compatible. The MEMS resonator offers better shock/vibration tolerance than quartz.
