Product details

12 MHz MEMS clock for industrial boards

The DSC1121BI2-012.0000 is a 12 MHz fixed-frequency MEMS oscillator from Microchip's DSC1121 series, delivering a CMOS output with enable/disable control. Rated across -40°C to 85°C with ±25 ppm frequency stability, this part suits outdoor telecom base stations, factory-floor PLCs, and engine-bay controllers where a quartz oscillator might drift or fail under vibration.

Supply rail and power budget

Operates from 2.25 V to 3.6 V, covering 2.5 V and 3.3 V logic rails without an external LDO.

Housed in a 6-VDFN package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm.

Frequently asked questions

Where can I buy DSC1121BI2-012.0000 and check stock?

This part is Active and available through independent distribution. Submit an RFQ with your target quantity; we confirm availability and current pricing at quote time. No stock-holding claim — sourced per order.

Is DSC1121BI2-012.0000 a direct drop-in replacement for a quartz oscillator?

Functionally yes — it provides a 12 MHz CMOS clock output with enable/disable, same as a quartz XO. The MEMS resonator is more shock-tolerant and starts faster, but the pinout and footprint (6-VDFN) must match the PCB land pattern. Verify the pad layout against your existing quartz oscillator's footprint before committing.

Is DSC1121BI2-012.0000 RoHS compliant?

RoHS compliance is standard for Microchip's DSC1121 series; the package is lead-free and the part is marked accordingly. Confirm the specific date-code compliance level on the datasheet or at RFQ.
