The DSC6003JI2B-025.0000T is a MEMS-based XO (standard oscillator) from Microchip's DSC60XXB series, delivering a fixed 25 MHz CMOS output in a compact 2.50 mm x 2.00 mm 4-VLGA package. AEC-Q100 qualification extends its reach to automotive domains — under-hood or cabin ECUs, ADAS sensors, and infotainment modules that require the reliability stress screening and PPAP documentation the automotive grade certifies.
The 1.71 V to 3.63 V supply range means this oscillator can run directly from a 1.8 V, 2.5 V, or 3.3 V rail without an intermediate LDO — a practical advantage when the MCU or SoC on the same board uses one of those voltages. Typical current draw is 1.3 mA max, keeping the thermal contribution negligible even in dense, unventilated enclosures.
