Supply flexibility and timing margin
The DSC6101CE1A-100.0000: Typical supply current is 3 mA — low enough that the oscillator's draw is negligible in a battery-backed or power-constrained design compared to a crystal-based equivalent at the same frequency.
Obsolete — sourcing through independent channels
Microchip lists the DSC6101CE1A-100.0000 as obsolete. No pin-compatible direct replacement from Microchip is documented.
