When the standby (power-down) function is asserted, the oscillator stops its internal MEMS drive and the output enters a high-impedance state, dropping the supply current from 8 mA max to 15 µA max. This allows the host processor to gate the clock during low-power sleep modes without an external load-switch. ## 4-VDFN package and board layout notes Housed in a 4-VDFN package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm, this oscillator occupies roughly the same footprint as a standard 3.2 x 2.5 mm SMD crystal. The 4-pin VDFN has a centre pad that should be connected to the ground plane through a single via to minimise loop inductance — the datasheet's recommended land pattern (not reproduced here) specifies 0.65 mm pad width and 1.10 mm pad pitch.","metaTitle":"DSC1001CI2-003.8000T Microchip MEMS XO, 3.8 MHz, AEC-Q100","metaDescription":"DSC1001CI2-003.8000T: Microchip MEMS XO, 3.8 MHz, CMOS output, AEC-Q100, -40°C to 85°C, standby function.
