Product details

The DSC1001BE1-020.0000T is a 20 MHz MEMS-based oscillator from Microchip's DSC1001 series, delivering a CMOS output with ±50 ppm frequency stability across its -20°C to 70°C operating range.

Supply voltage and power-down standby

Operating from a 1.8V to 3.3V supply rail, this oscillator can be powered directly from a 1.8V or 3.3V logic rail without an external regulator — the wide range covers common MCU and SoC I/O voltages.

Surface-mount footprint and tape-and-reel delivery

Housed in a 4-SMD, no-lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm — a standard 5×3.2 mm oscillator footprint that matches many quartz XO pinouts, easing a drop-in swap.

Frequently asked questions

Is the DSC1001BE1-020.0000T AEC-Q100 qualified?

Yes, it carries AEC-Q100 qualification, meaning it has passed automotive-grade reliability testing including temperature cycling, ESD, and latch-up. This qualifies it for use in automotive electronics such as ECUs, sensors, and infotainment modules.

What is the closest pin-compatible alternative to the DSC1001BE1-020.0000T?

Within the DSC1001 series, any 20 MHz variant with the same 5.0 mm x 3.2 mm 4-SMD package and CMOS output is pin-compatible. The key difference is temperature grade and stability — confirm your BOM's required temperature range and ±50 ppm stability before substituting.
