Product details

Active production — MEMS oscillator for automotive and industrial timing

AEC-Q100 qualification means this part is validated for automotive-grade reliability — suitable for under-hood or cabin electronics where vibration and thermal cycling are routine. The MEMS resonator replaces a quartz crystal inside the package, offering better shock and vibration tolerance than a traditional crystal oscillator, with a standard 6-SMD no-lead footprint that reflows on the same profile as a quartz XO.

Supply voltage range and power budget for rail planning

Operating from 2.25V to 3.6V, this oscillator spans the 2.5V and 3.3V logic rails without a separate regulator — the wide input range absorbs ±10% rail tolerance and ripple. Maximum supply current is 35 mA when enabled; the disable function drops consumption to 22 mA max, which helps meet standby power targets in automotive body controllers.

Package, footprint, and reflow considerations

Housed in a 6-SMD no-lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm — the same footprint as many standard quartz oscillators, so the PCB layout does not change when substituting a MEMS device.

Frequently asked questions

Does the DSC1121BI1-062.5000T have an enable/disable function?

Yes, the oscillator includes an Enable/Disable function. When disabled, the output is tri-stated and supply current drops to 22 mA max.

Is the DSC1121BI1-062.5000T a direct replacement for a quartz oscillator?

It is a functional replacement in the same 6-SMD no-lead footprint, but the MEMS resonator offers better shock and vibration tolerance than quartz. Electrical compatibility — supply voltage, output type (CMOS), and frequency (62.5 MHz) — matches standard XO specifications. Verify the enable/disable polarity and pinout against your existing quartz part before substitution.
