The DSC613RI2A-012ST: The three frequencies are factory-programmed to 12 MHz, 25 MHz, and 32.768 kHz — covering a typical MCU main clock, a high-speed peripheral clock, and a real-time-clock or sleep-mode tick, all in one device.
Maximum supply current is 6.5 mA across all three outputs active — a low enough draw that a small 0603 decoupling cap at the VDD pin is sufficient for most layouts.
The small footprint frees board space on dense multi-layer designs.
