Active MEMS XO for automotive and industrial timing
The DSC6003JI2B-027.0950 is a MEMS-based XO (standard oscillator) from Microchip's DSC60XXB series, delivering a fixed 27.095 MHz CMOS output. It is AEC-Q100 qualified, meaning it passes the automotive-grade stress and reliability tests — suitable for under-hood or cabin electronics where temperature swings and vibration are the norm. Frequency stability is rated at ±25 ppm across the full -40°C to 85°C industrial temperature range, which gives the system clock tree enough margin for a 27 MHz CAN or Ethernet PHY reference without needing an external trim capacitor.
Supply voltage and power budget
Operates from 1.71 V to 3.63 V, covering the common 1.8 V, 2.5 V, and 3.3 V logic rails. Typical supply current is 1.3 mA max — low enough that a shared LDO rail can feed this oscillator alongside other low-power peripherals without thermal concern.
Package and layout fit
Housed in a 4-VLGA package measuring 2.50 mm x 2.00 mm with a seated height of 0.89 mm. The small footprint and surface-mount design suit dense PCB layouts; the enable/disable function lets the firmware gate the clock output for power savings without a separate load switch.
