The DSC1502AI3A-4M000000 is a 4 MHz XO built around a MEMS resonator, not a quartz crystal — which means it survives the shock and vibration that cracks a quartz blank on a factory floor or in a motor-drive cabinet. Output is LVCMOS, so it drives the clock input of an MCU, FPGA, or Ethernet PHY directly without external level translation.
Supply flexibility and power-down standby
Accepts any rail from 2.5V to 3.3V — one BOM line covers 2.5V and 3.3V logic domains without a second oscillator variant. Max active current is 7.5 mA — the thermal budget in the exposed-pad package is comfortable even in a still-air enclosure.
