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.","metaTitle":"DSC1001CL1-040.0000T MEMS Oscillator","metaDescription":"Microchip DSC1001CL1-040.0000T MEMS XO, 40 MHz CMOS output, ±50 ppm stability, AEC-Q100, -40°C to 105°C. 4-VDFN package.
