Product details

Frequency stability is held to ±25 ppm over that entire span, which keeps the clock within tight tolerance for UART bit rates, CAN bus, and MCU PLL references without external trim components.

Supply voltage flexibility and enable/disable function

It is a current design-in part. No stock-holding claim — quoted per order.

6-VDFN package — board layout note

Housed in a 6-VDFN package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm — a compact footprint that fits under low-profile enclosures or alongside dense BGA clusters. No via-in-pad needed unless routing density forces it.

Frequently asked questions

Can I replace a 16.64 MHz quartz oscillator with the DSC1121DM2-016.6400?

Yes, if the quartz oscillator has a CMOS output and the same 6-pin footprint. The MEMS resonator provides better shock and vibration immunity than quartz, and the -55°C to 125°C range exceeds most quartz parts. Confirm the Enable/Disable logic polarity matches your circuit.

Does the DSC1121DM2-016.6400 support a 3.3 V supply?

Yes — the supply range is 2.25 V to 3.6 V, so 3.3 V is within spec. The same part also runs on 2.5 V rails without a separate regulator.

What is the frequency stability of the DSC1121DM2-016.6400?

±25 ppm over the full -55°C to 125°C range. This is tight enough for most MCU clocking and serial communication without external tuning.
