Product details

80 MHz MEMS clock source for industrial timing

Unlike quartz-based oscillators, the MEMS resonator is inherently more resistant to shock and vibration, making it a strong fit for motor drives, outdoor telecom, and factory-floor equipment where mechanical stress is a concern.

Supply voltage and output drive

The wide supply range of 2.25V to 3.6V lets this oscillator operate directly from 2.5V or 3.3V rails without an intermediate regulator, simplifying the power tree in mixed-voltage designs. CMOS output drives standard logic families directly; the Enable/Disable function allows the output to be tri-stated, pulling the supply current from 35 mA typical down to 22 mA max when the clock is gated off.

Package and footprint for PCB layout

Housed in a 6-SMD, No Lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm, this is a standard 5.0 x 3.2 mm oscillator footprint — the same land pattern used by many quartz oscillators, easing a drop-in replacement.

No end-of-life notification or successor has been announced.

Frequently asked questions

Can the DSC1121BI2-080.0000T replace a standard quartz oscillator at 80 MHz?

Yes. The 5.0 mm x 3.2 mm 6-SMD footprint is the same as many quartz oscillators, and the CMOS output is directly compatible. The MEMS resonator offers better shock and vibration tolerance than quartz, which can be an advantage in industrial environments.

Is the DSC1121BI2-080.0000T RoHS compliant?

RoHS compliance is standard for Microchip's DSC1121 series. The part is lead-free and compatible with lead-free soldering profiles. Confirm the specific RoHS certificate with your distributor at quote time.
