Blank-programmed — frequency set at your bench
The DSC8121DI2: This part ships as a blank (User Must Program) device — the customer programs the exact output frequency using Microchip's programming tool or factory programming service. That means one ordering code covers the entire 10 MHz to 170 MHz range; you stock a single part and program the frequency per BOM position, reducing inventory line items.
The small footprint leaves room for decoupling caps and routing on dense PCBs.
