MEMS oscillator for 66 MHz clock generation
The DSC1033DE1-066.0000T is a MEMS-based XO from Microchip's PureSilicon™ series, delivering a 66 MHz CMOS clock output from a 3.3V supply rail. It replaces a quartz crystal oscillator in the same footprint — the MEMS resonator eliminates quartz start-up time and is less sensitive to vibration and shock.
Package, footprint, and reflow fit
Housed in a 4-SMD no-lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm. The 0.098" x 0.079" land pattern matches standard 4-pad oscillator footprints — no special fan-out or via-in-pad required. For outdoor telecom enclosures or under-hood applications that see -40°C or +85°C, a wider-grade part from the DSC1033 family would be needed.
