MEMS oscillator for 41.5 MHz clock trees
The DSC1121AI1-041.5000T is a MEMS-based XO from Microchip's DSC1121 series, delivering a fixed 41.5 MHz CMOS output. Supply voltage spans 2.25 V to 3.6 V, covering 2.5 V and 3.3 V logic rails without an external regulator.
The 6-VDFN exposed pad package (7.00 mm x 5.00 mm, 0.90 mm seated height) requires a thermal pad on the PCB to pull heat from the die — the exposed paddle should be soldered to a ground plane for best thermal and electrical performance.
