100 MHz LVDS MEMS oscillator — AEC-Q100 rated
The DSC1123AE2-100.0000 is a 100 MHz LVDS XO built on a MEMS resonator, not a quartz crystal — the MEMS die delivers the same frequency accuracy (±25 ppm stability) with higher shock and vibration tolerance than a quartz equivalent, which matters for the AEC-Q100 qualification this part carries.
Microchip lists the DSC1123AE2-100.0000 as Active, so it remains a valid design-in choice for new builds and existing production.
Housed in a 6-SMD, no-lead exposed-pad package measuring 7.00 mm × 5.00 mm with a seated height of 0.90 mm. The exposed pad provides a low-thermal-resistance path to the PCB copper pour — in a 100 MHz LVDS oscillator drawing 32 mA, the pad keeps the junction temperature well below the 70 °C ambient limit. For under-hood or extended-temperature environments, a -40 °C to 105 °C variant from the same DSC1123 family would be the proper selection.
