Product details

48 MHz MEMS oscillator with full automotive temperature range

Rated AEC-Q100, this oscillator meets the reliability stress and PPAP requirements for automotive deployment — the temperature sweep and vibration tests match the demands of engine-bay and chassis-domain electronics. The supply voltage range of 2.25V to 3.6V lets it run directly from a 2.5V or 3.3V rail without an intermediate LDO, simplifying the power tree and reducing BOM count.

Housed in a 6-SMD no-lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm, this oscillator uses a standard 6-pad land pattern.
