The DSC1033CE1-002.0800 is a MEMS-based XO (standard oscillator) from Microchip's PureSilicon™ series, delivering a 2.08 MHz CMOS output from a 3.3V supply rail. For a 2.08 MHz clock, that is roughly ±104 Hz maximum drift — tight enough for a UART baud-rate generator or a low-speed MCU clock, but not for a precision RF reference.
The DSC1033 base product number covers a range of frequencies and stability grades; the CE1 suffix in this order code locks in the 2.08 MHz, ±50 ppm, -20°C to 70°C variant.
Housed in a 4-SMD, no-lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm. The 0.50 mm pitch and 4-pin layout are standard for small MEMS oscillators — the PCB land pattern matches the industry-standard 3.2x2.5 mm footprint used by many quartz and MEMS XOs. If the pin is unused, tie it high to Vdd to keep the oscillator running — floating it risks intermittent shutdown.
