The DSC1033BI1-024.0000T: This is a 24 MHz MEMS-based XO (standard oscillator) from Microchip's PureSilicon™ DSC1033 series, delivering a CMOS output from a 3.3V rail.
3 mA typical draw, 1 µA in standby
The MEMS resonator draws 3 mA typical during active operation — low enough that a 24 MHz clock tree on a 4-layer board doesn't need a dedicated regulator. When the standby (power-down) function is asserted, the supply current drops to 1 µA maximum, letting the oscillator sit on a battery bus without draining the cell during sleep intervals.
There is no NRND notice or last-time-buy window — it remains available for both new design-ins and ongoing BOM replenishment through independent distribution.
