MEMS oscillator at 8 MHz – commercial-grade timing
The DSC1033AC1-008.0000 is a MEMS-based XO (Standard) oscillator from Microchip's PureSilicon™ series, delivering a fixed 8 MHz CMOS output with ±50 ppm frequency stability across its 0°C~70°C commercial temperature range.
Package and board-fit – 4-SMD, no-lead exposed pad
Housed in a 4-SMD, No Lead Exposed Pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm — a standard surface-mount footprint that places cleanly with typical pick-and-place equipment. The exposed pad aids thermal conduction to the PCB; ensure the solder stencil aperture covers the pad per the datasheet land pattern to avoid tombstoning during reflow.
