Product details

The DSC1001DE1-020.0000 is a 20 MHz MEMS-based oscillator (XO) from Microchip's DSC1001 series, delivering a CMOS output with ±50 ppm frequency stability across its -20°C to 70°C operating range.

Supply range and standby power-down

The supply voltage spans 1.8V to 3.3V, so a single BOM line covers 1.8V, 2.5V, or 3.3V clock domains without a separate LDO — the oscillator self-biases across the range.

4-SMD no-lead package and board fit

Housed in a 4-SMD, no-lead package measuring 2.50 mm x 2.00 mm x 0.90 mm, this oscillator fits a standard 2.0 x 2.5 mm MEMS oscillator footprint — the same land pattern used by many SiTime and other MEMS XOs.

Frequently asked questions

Is the DSC1001DE1-020.0000 equivalent to other MEMS oscillators like the SiT8008 series?

The DSC1001DE1-020.0000 shares the same 2.5 x 2.0 mm footprint and 4-pin no-lead package as many SiT8008 variants, and both are MEMS-based with CMOS output. However, pin assignments and enable logic differ — always compare the datasheet's pinout before dropping one into a board designed for the other.

What does the standby (power-down) function do on this oscillator?

The standby function disables the output and puts the oscillator into a low-power state drawing 15 µA max. It is controlled by the enable pin — pulling it low shuts down the output; pulling it high or leaving it floating enables normal operation.

Is the DSC1001DE1-020.0000 suitable for automotive environments?

Yes — it carries an AEC-Q100 rating, which qualifies it for automotive-grade applications. The -20°C to 70°C temperature range suits cabin or climate-controlled modules, not under-hood or exterior locations where -40°C to 125°C is required.

How does the DSC1001DE1-020.0000 compare to the DSC1001DI1-020.0000?

Both share the same 20 MHz frequency, CMOS output, MEMS resonator, and DSC1001 series. The key difference is the operating temperature range: the DE1 suffix covers -20°C to 70°C, while the DI1 suffix covers -40°C to 85°C. Choose the DI1 variant if your application sees sub-zero or elevated temperatures outside the DE1's range.
