MEMS oscillator for automotive timing
The DSC6003JL3B-004.0096T is a MEMS-based XO (Standard) oscillator from Microchip's DSC60XX series, delivering a fixed 4.0096 MHz CMOS output. Its AEC-Q100 qualification means it has passed the automotive-grade reliability stress tests — temperature cycling, ESD, latch-up — required for under-hood or cabin ECU applications. The MEMS resonator is inherently more shock- and vibration-tolerant than a quartz crystal, which matters on a vehicle's engine bay or chassis-mounted PCB.
Supply voltage and power budget
The supply voltage range spans 1.71V to 3.63V, covering 1.8V, 2.5V, and 3.3V logic rails without an external regulator — one oscillator serves multiple voltage domains on the same board. Typical current draw is 1.3 mA max, which keeps the thermal contribution negligible in a sealed automotive module and simplifies the power distribution budget.
Package and enable/disable control
Housed in a 4-VLGA package measuring 2.50 mm x 2.00 mm, the oscillator fits tight PCB layouts common in ADAS cameras or sensor nodes. The enable/disable function lets the system shut down the clock output during low-power sleep modes — pulling the enable pin low stops the output without removing the supply rail, saving the 1.3 mA quiescent draw.
No pin-compatible second source is listed; the DSC60XX series is the only family carrying this exact frequency and package combination.
