100 MHz CMOS MEMS oscillator with AEC-Q100 qualification
AEC-Q100 qualification means this oscillator has passed the automotive-grade reliability stress tests (temperature cycling, ESD, latch-up) required for under-hood and chassis-domain electronics — not just cabin infotainment. The MEMS resonator replaces a quartz crystal with a silicon-based structure, giving better shock and vibration immunity compared to a traditional crystal oscillator — relevant for engine-mount or transmission-adjacent PCBs.
Standby power-down and supply flexibility
A standby (power-down) function disables the output and drops the supply current to 15 µA max — useful for battery-backed modules that need to wake the system clock on demand without a separate enable signal. The 1.8V–3.3V supply range covers common digital core and I/O voltages, so the same oscillator can feed a 1.8V FPGA bank and a 3.3V MCU clock input without a level translator. Maximum active supply current is 10.5 mA at 100 MHz — a modest draw that keeps the thermal budget low in a sealed enclosure.
Microchip lists the DSC1004BI2-100.0000T as an active product — no end-of-life notice, no last-time-buy deadline. It is suitable for both new designs and ongoing production replenishment. The 4-SMD no-lead package (5.00 mm × 3.20 mm footprint, 0.90 mm seated height) is a standard pinout shared across the DSC1004 family — board layout is compatible with other DSC1004 frequency variants.
