64 MHz MEMS clock source for industrial designs
The DSC1033CI1-064.0000 is a 64 MHz XO (Standard) oscillator from Microchip's PureSilicon™ MEMS family, delivering a CMOS output at 3.3V supply with ±50 ppm frequency stability. The MEMS resonator replaces a quartz crystal, offering faster start-up and better shock/vibration tolerance compared to a traditional crystal oscillator — relevant for portable or industrial equipment subject to mechanical stress.
Standby mode and power budget
Typical supply current is 4 mA during active operation, dropping to 1 µA when the standby (power down) function is asserted — the disable current is effectively leakage, making this oscillator a strong fit for battery-powered sensors or IoT nodes that sleep most of the time. The standby pin lets the system power down the clock tree without a separate load switch, saving board area and BOM cost in space-constrained designs.
Housed in a 4-SMD, No Lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a standard 3.2 x 2.5 mm oscillator footprint that matches many quartz oscillators, easing drop-in replacement in existing layouts. Surface-mount assembly with no exposed leads simplifies reflow soldering and reduces parasitic inductance at 64 MHz.
The part is currently in full manufacturing, suitable for both new designs and ongoing production.
