Product details

25.0008 MHz MEMS oscillator with AEC-Q100 qualification

The fractional MHz frequency is unusual — it lines up with specific serial data rates (e.g., 25.0008 MHz × 8 = 200.0064 Mbps) or video pixel clocks, so confirm your PLL multiplication factor before substituting a standard 25.0000 MHz part.

Automotive-grade timing for harsh environments

Rated AEC-Q100, this oscillator is qualified for automotive electronics — under-hood ECUs, infotainment clusters, and ADAS sensor modules where temperature cycling and vibration are routine. The MEMS resonator is inherently more shock-resistant than a quartz crystal, reducing startup failures in high-G environments.

Sourced through independent distribution, availability is confirmed at RFQ against your BOM quantity.

Supply voltage tolerance and standby power

Operating from 1.8V to 3.3V, the oscillator accepts any rail in that range without external regulation — useful when the same BOM needs to work across 1.8V and 3.3V logic domains. The Standby (Power Down) function drops supply current to 15 µA max, letting the system gate the clock during sleep modes without a separate enable switch.

Frequently asked questions

What is the frequency of DSC1001CI2-025.0008T?

25.0008 MHz. The fractional MHz is intentional — do not assume a standard 25.0000 MHz crystal can be swapped without checking the downstream PLL or data-rate tolerance.

Can I replace a 25.0000 MHz crystal with DSC1001CI2-025.0008T?

Not directly. A 25.0000 MHz crystal requires an external oscillator circuit; this is a self-contained XO with CMOS output. The 0.0008 MHz difference (32 ppm) may be within the PLL pull range, but verify the system's frequency tolerance before substituting.
