Four-frequency clock source in a single 5×3.2 mm package
The DSC400-1111Q0091KI1 is a MEMS-based XO (Standard) that generates four independent LVCMOS clock outputs from a single silicon resonator — 12 MHz, 24 MHz, 48 MHz, and 14.25 MHz — all in a 20-VFQFN package measuring 5.00 mm × 3.20 mm. The enable/disable function lets firmware gate unused outputs to save power.
The supply voltage spans 2.25 V to 3.6 V, so the oscillator can run from a common 2.5 V or 3.3 V rail without an intermediate LDO. The 0.90 mm seated height keeps it compatible with mezzanine-card stack-ups.
