Product details

40 MHz MEMS XO with AEC-Q100 and wide temperature range

The DSC1001BL2-040.0000T is a 40 MHz MEMS-based oscillator from Microchip's DSC1001 series, delivering CMOS output with ±25 ppm frequency stability across -40°C to 105°C — a fit for under-hood automotive ECUs and industrial controllers that see temperature swings beyond the commercial range. AEC-Q100 qualification means this part has passed the automotive-grade reliability stress tests (temperature cycling, ESD, latch-up) required for production vehicle programs — not just a datasheet claim, but a documented qualification.

Standby power-down and supply flexibility

A dedicated Standby (Power Down) function drops the supply current to 15 µA max when the enable pin is pulled low — useful for battery-backed modules or systems that cycle power between active sessions to save energy. The wide supply range of 1.8V to 3.3V lets this oscillator run directly from a 1.8V core rail or a 3.3V I/O rail without an extra regulator, simplifying the power tree on mixed-voltage designs.

Sourced through independent distribution; quoted to order against the BOM quantity.

Frequently asked questions

What is the frequency stability of the DSC1001BL2-040.0000T?

That's a common grade for CAN, LIN, and Ethernet PHY reference clocks — tight enough to keep bit timing within spec without a TCXO.

Is the DSC1001BL2-040.0000T AEC-Q100 qualified?

Yes — it carries AEC-Q100 rating, meaning it has passed the automotive-grade stress tests (temperature cycling, ESD, latch-up) required for production vehicle programs. Suitable for under-hood and cabin electronics.

What is the standby function of the DSC1001BL2-040.0000T?

The Standby (Power Down) function disables the output and drops the supply current to 15 µA max. Pull the enable pin low to enter standby; pull high for normal operation. Useful for battery-backed or intermittently powered modules.
