The DSC1121CL5-080.0000T is a MEMS-based XO (Standard) from Microchip's DSC1121 series, delivering an 80 MHz CMOS output with ±10 ppm frequency stability across -40°C to 105°C. Its 2.25V to 3.6V supply range lets it run from either a 3.3V or 2.5V rail without an extra regulator — useful on mixed-voltage boards where the oscillator rail is a secondary supply. The 6-VDFN package (3.20 mm x 2.50 mm, 0.90 mm seated height) keeps the footprint small enough for space-constrained designs like compact Ethernet switches or industrial sensor nodes.
