AEC-Q100 MEMS oscillator for automotive clock trees
The DSC6003JL3B-007.3728 is a MEMS-based XO (standard oscillator) from Microchip's DSC60XX series, delivering a 7.3728 MHz CMOS output from a 4-VLGA package. Its AEC-Q100 rating means it has passed the temperature, reliability, and PPAP requirements for automotive-grade ICs — suitable for under-hood and chassis-domain ECUs where a quartz crystal's shock sensitivity or temperature drift would be a risk.
Supply voltage flexibility and power budget
Operates across a 1.71V to 3.63V supply range, covering 1.8V, 2.5V, and 3.3V rails without a separate LDO. Typical supply current is 1.3 mA max — low enough for always-on modules like a body controller or gateway that must keep the CAN clock alive during sleep.
Enable/Disable function for power sequencing
The Enable/Disable pin lets the system shut down the oscillator output during low-power modes, cutting the clock to downstream peripherals without removing the supply rail. This is useful in automotive ECUs that sequence power domains to meet quiescent current targets.
