Blank programmable — user sets the frequency
The DSC8001DL5 ships as a blank (unprogrammed) device — the user must program the target frequency within the 1 MHz to 150 MHz range using Microchip's programming tools before assembly. This approach lets a single BOM line cover multiple frequency variants; the same blank part can be programmed to 25 MHz, 50 MHz, or 100 MHz depending on the production run, reducing inventory SKU count.
4-SMD no-lead footprint
The no-lead land pattern simplifies reflow profiling — the pad geometry matches standard JEDEC footprint recommendations for 2.5 x 2.0 mm SMD oscillators.
