Product details

Why a MEMS oscillator instead of quartz

This DSC1101DL2-054.0000T uses a MEMS resonator rather than a quartz crystal — the MEMS structure is inherently more shock- and vibration-tolerant, and the frequency is set during wafer-level trim, so there is no crystal aging drift to budget in a 10-year field life.

Rated for -40 to 105°C, this oscillator fits outdoor telecom cabinets, factory-floor controllers, and engine-bay electronics where a commercial-grade 0-70°C part would drift out of spec on a hot afternoon.

Housed in a 6-VDFN package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm — the small footprint and low profile suit space-constrained PCBs like PCIe add-in cards or compact IoT modules.

Frequently asked questions

How do I use the standby function on the DSC1101DL2-054.0000T?

The standby (power down) pin is a logic input — driving it low (or high, depending on the configuration variant) disables the output and reduces supply current to 95 µA max. Consult the DSC1101 series datasheet for the exact polarity and timing requirements.
