Product details

16.384 MHz MEMS clock — what it replaces and where it fits

The DSC1121BI2-016.3840 is a 16.384 MHz MEMS-based oscillator (XO) with a CMOS output, designed as a drop-in replacement for quartz-based oscillators in the same 6-SMD, No Lead footprint (5.00mm x 3.20mm).

Supply range, temperature grade, and output drive

The supply voltage spans 2.25V to 3.6V, covering common 2.5V and 3.3V logic rails without an external regulator — one less component on the BOM. It suits outdoor base stations, factory-floor controllers, and under-hood electronics where the ambient can climb well above room temperature. The CMOS output swings rail-to-rail and can drive up to 22 mA max into the load — enough to feed multiple clock inputs on a small PCB without a separate buffer.

Frequently asked questions

How can I order DSC1121BI2-016.3840 or check availability?

The 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 — every order is quoted to order.

Is DSC1121BI2-016.3840 RoHS compliant?

The evidence does not list a RoHS compliance statement. Confirm with the manufacturer's latest documentation or request a certificate of compliance at RFQ.

Can DSC1121BI2-016.3840 replace a standard 16.384 MHz quartz oscillator?

Yes — it is a MEMS-based drop-in replacement for quartz oscillators in the same 6-SMD, No Lead footprint (5.00mm x 3.20mm). The MEMS resonator offers better shock and vibration immunity than quartz, which is useful in rugged environments.
