Its silicon resonator replaces a quartz crystal, giving it better shock and vibration tolerance than a traditional crystal oscillator — useful on a factory floor or in an engine bay where mechanical stress is routine. The part is AEC-Q100 qualified, meaning it has passed the automotive-grade stress tests (temperature cycling, ESD, latch-up) required for under-hood or cabin electronics. ## Supply voltage and output compatibility Supply voltage spans 1.8V to 3.3V, so the same oscillator can serve a 1.8V MCU core clock, a 2.5V FPGA reference, or a 3.3V peripheral bus without a separate level translator. The CMOS output swings rail-to-rail, which keeps the rising edge clean into a standard digital input. Frequency stability is ±50ppm over the full temperature range — tight enough for a CAN bus or USB clock without needing an external trim capacitor. The standby (power-down) function drops supply current to 15µA max, letting the system gate the oscillator off during sleep modes. Housed in a 4-SMD No Lead package measuring 3.20mm x 2.50mm with a seated height of 0.90mm. The small footprint and low profile suit space-constrained PCBs. The No Lead construction means the terminations are flush with the package body — rework with hot air is straightforward if you preheat the board to 100°C to avoid pad lifting. No direct pin-compatible replacement is listed — the DSC1001 series is the current generation.","metaTitle":"DSC1001CI1-033.3330T – Microchip MEMS XO, 33.333 MHz, CMOS","metaDescription":"Microchip DSC1001CI1-033.3330T: MEMS-based XO, 33.333 MHz, CMOS output, 1.8-3.3V supply, -40°C to 85°C, AEC-Q100 qualified.
