CMOS output with Enable/Disable control: pulling the enable pin low drops supply current from 35 mA to 22 mA, which matters for battery-powered designs that can tolerate a short wake-up time. ## Package and footprint — 6-SMD no-lead, 5.0 × 3.2 mm Housed in a 6-SMD no-lead package measuring 5.00 mm × 3.20 mm with a seated height of 0.90 mm — this is the same footprint as many quartz oscillators, so it drops onto existing PCB layouts without a board spin.","metaTitle":"DSC1121BM1-032.0000T MEMS Oscillator – 32 MHz, CMOS","metaDescription":"Microchip DSC1121BM1-032.0000T: 32 MHz MEMS XO, CMOS output, 2.25-3.6V supply, ±50ppm stability, -55 to 125°C.

This gives the DSC1121BM1-032.0000T better shock and vibration tolerance (no quartz crystal to crack), faster start-up, and no frequency drift from quartz aging. The trade-off is that MEMS oscillators typically have slightly higher phase noise than a high-end quartz OCXO, but for most MCU and digital logic clocking the difference is negligible."},{"question":"Is the DSC1121BM1-032.0000T RoHS compliant?","answer":"The evidence does not explicitly state RoHS compliance status.
