Why the AEC-Q100 rating matters for this MEMS oscillator
The DSC1001CE2-025.0000 carries AEC-Q100 qualification — the automotive IC stress test that covers temperature cycling, ESD, and latch-up. That means this 25 MHz oscillator can sit on a board that sees under-hood or cabin thermal profiles, not just a climate-controlled lab bench.
Standby function — when to use the power-down pin
The standby (power-down) pin on the DSC1001CE2-025.0000 drops the supply current from 6.3 mA max to 15 µA max. That two-orders-of-magnitude reduction is what lets a battery-backed ECU or a sleep-mode sensor node keep the oscillator off until a wake event needs the clock. With CMOS output and a 1.8–3.3 V supply range, the standby pin is compatible with a GPIO from any modern MCU — no level translator needed to gate the oscillator.
Supply range and temperature envelope — fit check
The 1.8 V to 3.3 V operating range means this single oscillator covers 1.8 V logic, 2.5 V I/O, and 3.3 V peripheral rails without a separate supply regulator. If the board sees -40°C or 105°C continuously, this is not the right variant.
Package and board layout notes
The 4-SMD no-lead package measures 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a standard 3.2 x 2.5 mm oscillator footprint.
