64 MHz MEMS XO with standby — 2.5 x 2.0 mm footprint
The DSC1033DI1-064.0000 is a 64 MHz XO (Standard) from Microchip's PureSilicon™ MEMS oscillator family, delivering a CMOS output at 3.3V with ±50ppm frequency stability across -40°C to 85°C. Its MEMS base resonator and 4-SMD no-lead package (2.50mm x 2.00mm, 0.90mm seated height) suit space-constrained, vibration-tolerant designs — the MEMS die is inherently more shock-resistant than a quartz crystal.
A board-level redesign may be required if a functional equivalent is needed.
