33.333 MHz MEMS oscillator with AEC-Q100 qualification
AEC-Q100 qualification means this part has passed the automotive-grade stress tests (temperature cycling, ESD, latch-up) required for under-hood and cabin electronics — a step up from commercial oscillators that lack the reliability screening. The MEMS base resonator replaces a quartz crystal, giving better shock and vibration immunity and a faster start-up time — useful in automotive and industrial environments where mechanical stress is a concern.
Supply voltage flexibility and enable/disable control
Operates from a single 1.8V to 3.3V supply, covering the common digital rail voltages without needing an extra regulator — a single BOM line serves 1.8V, 2.5V, or 3.3V logic domains. The Enable/Disable function (pin 1) lets the system shut down the oscillator to 15 µA max supply current, saving power in sleep modes or during battery-backed operation. Active current draw is 7.2 mA max at 33.333 MHz — low enough for a shared 3.3V rail with an MCU or PHY without thermal concerns.
Package and board layout for the 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 footprint that matches many quartz XO footprints, simplifying a drop-in replacement. Surface-mount assembly with no leads means no through-hole vias under the part — the pad pattern is a simple 4-pad land with a central thermal via array, easy to route on a two-layer board.
