Product details

16.384 MHz MEMS oscillator with wide supply tolerance

The DSC1121BI2-016.3840T is a MEMS-based XO (Standard) oscillator delivering a 16.384 MHz CMOS output — a common reference frequency for 10/100 Ethernet PHYs, CAN controllers, and UART clocking. The 2.25V to 3.6V supply range means it can run from a 2.5V or 3.3V rail without an extra regulator, simplifying the power tree.

The MEMS resonator base inherently resists shock and offers faster startup than a quartz crystal — no load-capacitance matching or negative-resistance margin calculation needed.

The 6-SMD no-lead package (5.00mm x 3.20mm footprint, 0.90mm seated height) is a standard MEMS oscillator pinout, compatible with many quartz oscillator footprints for drop-in replacement.

Frequently asked questions

Can DSC1121BI2 replace a standard quartz oscillator in my design?

Yes — the DSC1121BI2 uses a MEMS resonator instead of a quartz crystal, but the output is standard CMOS and the 6-SMD package is footprint-compatible with many quartz XO packages. No external load capacitors are needed, and the supply voltage range (2.25V to 3.6V) covers common logic rails. The Enable/Disable pin maps to the standard oscillator function.

What is the exact frequency and output type of DSC1121BI2-016.3840T?

The exact output frequency is 16.384 MHz, and the output type is CMOS (standard square-wave).
