Housed in a 6-SMD no-lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm, the footprint matches industry-standard 5x3.2 mm oscillator pads — a drop-in replacement for quartz oscillators in the same form factor, provided the supply and output type align.","metaTitle":"DSC1121BM1-050.0000T MEMS Oscillator 50 MHz CMOS AEC-Q100","metaDescription":"Microchip DSC1121BM1-050.0000T XO, 50 MHz CMOS output, AEC-Q100 qualified, -55°C to 125°C, 2.25V-3.6V supply.
