What this MEMS oscillator brings to a 40 MHz clock line
Its supply voltage range of 1.8V to 3.3V means the same part number works across a 1.8V core rail, a 2.5V I/O bank, or a 3.3V peripheral bus — one BOM line covers multiple voltage domains.
Temperature grade and automotive qualification
A production ECU or ADAS sensor module can use it without an additional qualification delta.
At 40 MHz the oscillator draws 8 mA max from the supply rail — about 26 mW at 3.3 V — which is typical for a MEMS XO at this frequency and leaves thermal margin in the 4-VDFN package. Pull the enable pin low and the output goes high-impedance; the rest of the board can sleep while the oscillator sits ready to wake on a pin toggle.
Housed in a 4-VDFN package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a compact, low-profile footprint that fits under a mezzanine card or inside a handheld enclosure. The 4-pin VDFN has a centre pad that should be connected to the ground plane for thermal relief, though the 8 mA draw rarely needs it.
