The DSC1033DI2-007.3728T is a MEMS-based XO from Microchip's PureSilicon™ series, delivering a 7.3728 MHz clock with CMOS output in a 4-SMD no-lead package.
The 4-SMD no-lead package measures 2.50 mm × 2.00 mm with a seated height of 0.90 mm. The compact footprint suits space-constrained PCBs in portable instruments, IoT nodes, or multi-channel data-acquisition modules.
This is the total allowable deviation including temperature, supply voltage, and aging.
The DSC1033 uses a MEMS resonator instead of a quartz crystal. MEMS oscillators typically offer faster start-up, better shock and vibration tolerance, and a smaller footprint. The ±25 ppm stability is comparable to a standard quartz XO; for tighter stability (e.g., ±10 ppm) a quartz TCXO or higher-grade MEMS part would be required.
