The DSC1001AI2-033.3330T is a 33.333 MHz MEMS-based XO (Standard) oscillator from Microchip's DSC1001 series. The ±25ppm frequency stability keeps the clock edge within tight timing margins for CAN, LIN, or Ethernet PHY reference without needing a TCXO.
Rated for 1.8V to 3.3V supply, this oscillator runs from the same rail as a 1.8V MCU core or a 3.3V I/O bank — no level translator needed for the clock line.
Standby function cuts current to 15µA
Pull the enable pin low to shut off the output — useful for battery-powered modules that sleep between sensor reads. The MEMS resonator starts fast, so wake-up latency is typically under a few milliseconds.
Industrial temperature range and surface-mount package
The 4-SMD, no lead exposed pad package measures 7.00mm x 5.00mm with a seated height of 0.90mm — standard footprint for 7x5 mm oscillators, so the PCB layout matches many quartz-based parts. Surface-mount means it runs through reflow; check the MSL before the oven.
