Package and board integration
The DSC1123AI1-212.5000T: Surface-mount only; hand-soldering is possible with a hot-air station and a fine-tip iron for the perimeter pads, but the exposed pad reflow is best done with a solder paste stencil.
Power budget for the clock tree
Draws 32 mA max from the supply when enabled — that's the total current for the oscillator core plus the LVDS output driver. In a multi-clock system, this one oscillator replaces a quartz crystal plus a separate LVDS fanout buffer, saving both board area and BOM line count. The wide supply tolerance also means you don't need a dedicated LDO for the oscillator rail if the main supply is within 2.25V to 3.63V.
