Product details

MEMS oscillator with ±10 ppm stability

The MEMS resonator eliminates the quartz crystal start-up and aging drift concerns — the stability spec holds from first power-up through the part's operating life.

Supply voltage and output drive

Operates from a 2.25V to 3.6V supply, so it can run directly from a 2.5V or 3.3V rail without an external regulator. The CMOS output sinks and sources up to 35 mA max — enough to drive a single clock load or a small fan-out tree on a short PCB trace.

Enable/Disable function and power savings

The Enable/Disable function (pin 1) lets the system shut down the oscillator output while keeping the MEMS resonator biased. When disabled, supply current drops to 22 mA max — useful for power-sensitive designs that need to gate the clock without a full power cycle.

Package and board layout

Housed in a 6-VDFN exposed-pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm.

Active production status

No last-time-buy or end-of-life notice has been issued. Sourced through independent distribution; availability and lead time confirmed at RFQ.

Frequently asked questions

Is the DSC1121AI5-041.5000 a drop-in replacement for a standard quartz oscillator?

Yes — the DSC1121AI5-041.5000 is pin-compatible with standard 7.0 mm x 5.0 mm quartz oscillators in a 6-pad footprint. The MEMS resonator eliminates quartz start-up delay and frequency aging, but the output logic (CMOS) and supply range (2.25V–3.6V) match typical quartz XO specifications. Confirm the Enable/Disable logic polarity on your existing quartz part — the DSC1121 uses active-low enable by default.
