Four clock domains from one MEMS resonator
The DSC400-3333Q0104KI1T packs four independent LVDS clock outputs — 125 MHz, 100 MHz, 200 MHz, and 156.25 MHz — into a single 5.0 mm x 3.2 mm 20-VFQFN package. Instead of buying four separate oscillators and routing four supply bypasses, you place one device that generates all four frequencies from a MEMS resonator. That saves three BOM lines and the board area they occupied. Each output has its own Enable/Disable pin, so unused clock domains can be gated off without external logic — useful for power-sensitive designs or test modes where only a subset of clocks is needed.
The supply voltage range of 2.25 V to 3.6 V covers both 2.5 V and 3.3 V logic rails without a separate LDO — one rail feeds the oscillator, and the LVDS outputs swing rail-to-rail within that window.
