33.3333 MHz MEMS XO — ±50 ppm stability with AEC-Q100
The DSC1001DE1-033.3333T is a MEMS-based XO (Standard) from Microchip's DSC1001 series, delivering a 33.3333 MHz CMOS output with ±50 ppm frequency stability across its full operating range. The MEMS resonator eliminates the cold-start frequency drift and shock sensitivity typical of quartz crystals — particularly relevant for engine-bay or chassis-mounted modules that see wide temperature swings and mechanical stress.
Supply range, standby mode, and disable current
Active consumption is 7.2 mA max at 33.3333 MHz, which keeps the thermal budget low in the compact 2.5 mm × 2.0 mm 4-SMD package.
The 4-SMD no-lead footprint (2.50 mm × 2.00 mm) is a standard MEMS oscillator layout — the same pad pattern used by many SiTime and Microchip DSC-series parts, so a board layout that accepts one often accepts the other without a spin.
