MEMS clock source for automotive infotainment and industrial control
The DSC6001JE3B-050.0000T is a MEMS-based XO (Standard) oscillator from Microchip's DSC60XXB series, delivering a 50 MHz CMOS output with ±20 ppm frequency stability across the -20°C to 70°C operating range. Rated AEC-Q100, this part targets automotive cabin-domain applications such as infotainment head units and ADAS camera modules where the commercial temperature grade matches the interior environment. The MEMS base resonator eliminates quartz crystal startup delay and aging drift, giving a deterministic clock source that powers up at the correct frequency from the first cycle.
Supply tolerance and power budget for shared-rail designs
Operating from 1.8V to 3.3V, the oscillator can share a rail with a 1.8V MCU core or a 3.3V I/O bank without a dedicated LDO — the wide input range absorbs ±10% supply variation typical of automotive battery rails.
Enable/Disable function and 4-VLGA footprint planning
Housed in a 4-VLGA package measuring 2.50 mm x 2.00 mm with a seated height of 0.89 mm, the footprint demands a solid ground plane under the package and a 100 nF decoupling cap within 1 mm of the supply pin to keep supply ripple from modulating the MEMS resonator.
