Product details

The DSC6101JI2B-049.1520T: Unlike a quartz crystal, the MEMS resonator has no aging drift or start-up time to budget — the oscillator is stable at the rated ±25 ppm from the moment the supply hits the minimum threshold.

Typical current draw is 3 mA — low enough for always-on modules in battery-backed systems, yet the CMOS output drives standard logic loads without buffering. The Enable/Disable function gates the output when the pin is pulled low, cutting supply current to near-zero.

Active lifecycle — no design-in risk

The MEMS construction also avoids the supply chain variability of quartz blanks.

Frequently asked questions

What is the DSC6101JI2B-049.1520T used for?

It is a 49.152 MHz MEMS oscillator (XO) with CMOS output, commonly used as a reference clock for USB 3.0 controllers, audio codecs, Ethernet PHYs, and automotive ECUs that need a stable frequency without a quartz crystal's aging or shock sensitivity.
