MEMS oscillator with automotive-grade qualification
The DSC1003CI2-025.0000 is a MEMS-based XO (Standard) from Microchip Technology's DSC1003 series, delivering a 25 MHz CMOS output with ±25 ppm frequency stability. The MEMS resonator gives it faster startup and better shock/vibration tolerance than a quartz crystal oscillator — relevant for automotive and industrial environments where quartz can suffer micro-cracks. That covers under-hood and cabin electronics where the ambient temperature swings beyond what a commercial-grade oscillator can handle.
Supply voltage flexibility and standby power
The supply voltage range spans 1.7V to 3.6V, so the same oscillator can serve 1.8V and 3.3V logic domains without a voltage translator. Maximum active current is 6 mA; in standby (power-down) mode the disable current drops to 15 µA, which matters for battery-backed or sleep-mode circuits where every microamp counts.
Package and footprint for automated assembly
Housed in a 4-SMD, no-lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm, the DSC1003CI2-025.0000 is a surface-mount device suited for reflow soldering. The small footprint and low profile fit space-constrained PCBs in automotive ECUs or portable instrumentation.
