What this oscillator is — and what it is not
The DSC1100BL5-PROGT is a blank, user-programmable oscillator from Microchip's DSC1100 series — it ships without a factory-set frequency. This means the default frequency is undefined until you program it. If your BOM line expects a fixed-frequency oscillator, this part will not oscillate out of the tube. The 6-VDFN package (5.00mm x 3.20mm, 0.90mm seated height) is a standard MEMS oscillator footprint, compatible with many fixed-frequency oscillators in the same land pattern.
Programming workflow — what you need
Because the part is blank, you need a programming tool — Microchip's TimeFlash or a compatible in-system programmer — to set the output frequency before the oscillator can drive a clock load.
