Current draw and supply flexibility
The DSC6023HI2A-00A9T: The oscillator draws 1.3 mA typical at max supply — low enough that a coin cell or small LDO can power it without thermal concern. The 1.71 V minimum supply means it works in sub-1.8 V systems where a standard 3.3 V oscillator would need a level translator or separate rail.
Obsolete — sourcing through independent channels
For a BOM that already uses this dual-frequency oscillator, the last-time-buy window has closed, so stock is limited to what remains in the distribution pipeline.
