Product details

37.125 MHz MEMS oscillator with automotive-grade qualification

The DSC1001BI2-037.1250T is a Microchip MEMS-based XO delivering a fixed 37.125 MHz CMOS output — the exact frequency is baked into the part number, so no external tuning components are needed. Rated AEC-Q100, it is qualified for automotive stress and reliability requirements, making it a fit for under-hood or cabin-domain clocking where temperature cycling and vibration are routine. The standby (power-down) function drops supply current to 15 µA max when disabled — useful for modules that sleep between CAN bus wake-ups or ignition cycles.

Sourced through independent distribution, it is quoted to order against the BOM quantity. The 4-SMD no-lead package (5.00 mm x 3.20 mm footprint, 0.90 mm seated height) is a standard MEMS oscillator land pattern — no special fan-out or via-in-pad required.

Frequently asked questions

What is the exact frequency of DSC1001BI2-037.1250T?

The oscillator outputs a fixed 37.125 MHz CMOS clock — the frequency is encoded in the part number suffix and requires no external configuration.

Is DSC1001BI2-037.1250T AEC-Q100 qualified?

Yes, it carries AEC-Q100 rating, which qualifies it for automotive-grade stress and reliability testing including temperature cycling and ESD robustness.

Does DSC1001BI2-037.1250T have a standby function?

Yes, the standby (power-down) function disables the output and drops supply current to 15 µA max, suitable for battery-backed or sleep-mode applications.

What is the closest pin-compatible alternative to DSC1001BI2-037.1250T?

The DSC1001 series shares the same 4-SMD package and pinout across frequency variants. A different frequency in the same series (e.g., DSC1001BI2-025.0000T) is pin-compatible but changes the output clock — verify the BOM frequency before substituting.
