Product details

The Enable/Disable function lets the system hold the output in high-impedance state when the clock is not needed, pulling 22 mA max in disable versus 35 mA max when active.

Wide supply range and MEMS reliability

Operating from 2.25 V to 3.6 V, this oscillator covers 2.5 V and 3.3 V logic rails without a separate regulator. The MEMS resonator is inherently more shock- and vibration-tolerant than quartz crystals, which matters for equipment that sees frequent mechanical stress or high-g environments.

Sourced through independent distribution; pricing and availability confirmed at RFQ against your BOM quantity. The tube package is the standard delivery format—if your pick-and-place prefers tape and reel, the suffix variant (DSC1121BM1-032.0000T) is the reeled version of the same device.

Frequently asked questions

How can I order DSC1121BM1-032.0000 or check availability?

This part is Active and available through independent distribution. No stock-holding claim is made—each order is sourced per your BOM line.

Does DSC1121BM1-032.0000 require an external load capacitor?

No. The MEMS oscillator has an internal PLL and output driver—the CMOS output swings rail-to-rail and does not need external load capacitors like a bare quartz crystal would. The specified frequency stability (±50 ppm) is met with the supply decoupling capacitors recommended in the datasheet.

How does DSC1121BM1-032.0000 compare to DSC1121BM1-032.0000T?

The electrical specifications are identical. The only difference is the shipping package: DSC1121BM1-032.0000 ships in a tube, while DSC1121BM1-032.0000T ships in tape and reel. Choose the reel suffix if your assembly line uses automated pick-and-place feeding from a reel.

Is DSC1121BM1-032.0000 RoHS compliant?

Microchip Technology lists this part as RoHS compliant. The 6-SMD package is lead-free compatible with standard reflow profiles. No additional halogen or antimony restrictions are stated in the available records.
