That dual-frequency capability in a single 4-VDFN package made it attractive for designs needing a real-time clock reference alongside a main system clock without a second oscillator.
Typical supply current is 3 mA max — a MEMS advantage over quartz for low-power battery-backed clock trees.
Microchip does not publish an official successor for this exact order code. The DSC61XX family includes many active dual-output MEMS XOs in the same 4-VDFN package with similar supply and stability ratings, but the exact 32.768 MHz / 56 MHz frequency pair may not be replicated on a current-orderable variant. A parametric search on the family's active parts is the practical path to a drop-in candidate.
