The enable pin is the standby control; when pulled low the output goes high-impedance and the internal oscillator stops. The 4-SMD, no-lead exposed-pad package measures 7.00 mm × 5.00 mm with a seated height of 0.90 mm. The four pads are standard: enable, ground, output, and Vdd. No via-in-pad is required; a single via per pad outside the footprint is sufficient.","metaTitle":"DSC1033AE1-040.0000 40 MHz MEMS XO, 3.3 V CMOS","metaDescription":"DSC1033AE1-040.0000: 40 MHz MEMS oscillator, 3.3 V, CMOS output, ±50 ppm, -20°C to +70°C.
