Product details

The DSC1001DE2-037.1250T is a 37.125 MHz MEMS-based oscillator (XO) from Microchip Technology's DSC1001 series, delivering a CMOS output with ±25ppm frequency stability.

Supply voltage range and standby power-down

The oscillator operates from a single supply rail spanning 1.8V to 3.3V, which covers the common logic voltages used in modern MCUs, FPGAs, and SoCs — no external level translator is needed when moving between a 1.8V core and a 3.3V I/O bank. A standby (power-down) function is built in: when the enable pin is driven low, the oscillator stops and draws only 15µA maximum, compared to 7.2mA when running. This makes the part suitable for battery-powered or duty-cycled systems where the clock can be gated off during sleep modes.

Temperature grade and package footprint

The 4-SMD no-lead package measures 2.50mm x 2.00mm with a seated height of 0.90mm, a compact footprint that fits tight PCB layouts.

Microchip lists the DSC1001DE2-037.1250T as Active (current production).

Frequently asked questions

Is the DSC1001DE2-037.1250T a MEMS oscillator, and what advantage does that bring?

Yes, the base resonator is a MEMS die rather than a quartz crystal. MEMS oscillators are inherently more resistant to vibration and mechanical shock, they start up faster (typically under 5 ms), and they do not require a load capacitor or external feedback resistor — the resonator and the oscillator circuit are integrated into the same package. This simplifies PCB layout and reduces BOM count compared to a quartz-based XO.

Does the DSC1001DE2-037.1250T have a standby function, and how is it controlled?

Yes, the part includes a standby (power-down) function. When the enable pin is driven low, the oscillator output is disabled and the supply current drops to 15µA maximum.

Is the DSC1001DE2-037.1250T AEC-Q100 qualified?

Yes, the oscillator carries an AEC-Q100 rating, meaning it has passed the automotive-grade reliability stress tests including temperature cycling, ESD, and latch-up immunity. It is suitable for deployment in vehicle electronics such as infotainment, telematics, and ADAS modules.
