Product details

66.666 MHz MEMS oscillator — obsolete, sourced per RFQ

The DSC1033DI1-066.6660T is a 66.666 MHz MEMS-based XO (Standard) from Microchip's PureSilicon™ series, delivering a CMOS output from a 3.3V rail with ±50 ppm frequency stability.

Microchip lists the DSC1033DI1-066.6660T as obsolete.

Package and footprint — 4-SMD no-lead

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 small footprint suits space-constrained boards in portable or densely populated designs. Surface-mount assembly; the 0.90 mm max height allows placement under low-profile enclosures or on the back side of a PCB.
