Product details

25 MHz MEMS oscillator with ±25 ppm stability

AEC-Q100 qualification means this oscillator is characterized for automotive-grade reliability — suitable for under-hood or cabin-domain electronics where temperature cycling and vibration are part of the operating profile. The standby (power down) function drops supply current to 15 µA max when disabled, making it a fit for battery-backed or intermittent-duty systems where the clock tree must be gated off between active periods.

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

Package and supply voltage flexibility

Housed in a 4-VDFN package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm — a low-profile footprint that fits tight board stacks and aligns with standard 5x3.2 mm oscillator land patterns.

Frequently asked questions

What is the frequency stability of DSC1004BI2-025.0000?

For a 25 MHz carrier, that translates to a maximum frequency deviation of ±625 Hz — tight enough for most microcontroller and interface clocking needs, though not suitable for precision RF or timekeeping where sub-ppm stability is required.

Is DSC1004BI2-025.0000 compatible with a standard 25 MHz quartz oscillator?

Yes, it is a drop-in functional replacement for a 25 MHz quartz oscillator with CMOS output, provided the board footprint matches the 4-VDFN package (5.00 mm x 3.20 mm). The MEMS resonator is more shock- and vibration-tolerant than a quartz crystal, which can matter in automotive or industrial environments.

Does DSC1004BI2-025.0000 have a standby mode?

Yes, it includes a Standby (Power Down) function. When the enable pin is de-asserted, the output is disabled and the supply current drops to 15 µA max, compared to 6.5 mA max during active operation. This is useful for battery-powered or duty-cycled systems where the oscillator is gated off between active periods.
