125 MHz MEMS oscillator with automotive qualification
Its AEC-Q100 rating means it has passed the automotive-grade reliability stress tests — temperature cycling, ESD, latch-up — required for under-hood and cabin electronics. The standby (power down) function drops supply current to 15 µA max, letting the oscillator sleep when the ECU is off without a separate enable signal.
Supply voltage flexibility and power budget
Operating from 1.8V to 3.3V, this oscillator works across the common logic rails found in automotive microcontrollers and FPGAs. The 10.5 mA max supply current at 125 MHz is the full-speed draw; in standby the disable current is 15 µA, so a battery-backed RTC or wake-up circuit sees negligible drain during sleep.
Package, footprint, and board integration
Housed in a 4-SMD, No Lead Exposed Pad package measuring 7.00mm x 5.00mm with a seated height of 0.90mm. The exposed pad provides a thermal path to the PCB ground plane — a solid via array under the pad keeps the junction temperature within limits during continuous 125 MHz operation. Surface-mount assembly with standard reflow profiles; the MEMS resonator is inherently more shock and vibration tolerant than a quartz crystal, which matters for engine-bay and chassis-mounted ECUs.
Sourced through independent distribution; quoted to order against the BOM quantity. No direct pin-compatible replacement is recorded — the DSC1004AI5-125.0000T is the specific automotive-grade variant at this frequency and stability.
