Four clocks from one MEMS oscillator
The DSC400-1311Q0076KE2 packs four independent output frequencies into a single 20-VFQFN package — 24 MHz, 25 MHz, 200 MHz, and 150 MHz — using a MEMS resonator instead of a quartz crystal. Two outputs are LVCMOS (24 MHz and 25 MHz) for logic or interface clocks; the other two are LVDS (200 MHz and 150 MHz) for high-speed serial links or SerDes reference clocks.
Supply rail flexibility and enable control
The wide supply range of 2.25V to 3.6V lets this oscillator run directly from a 2.5V or 3.3V rail — no extra LDO needed.
The 20-VFQFN with exposed pad (5.00 mm x 3.20 mm, 0.90 mm height) requires a thermal pad on the PCB for heat dissipation — the centre pad must be soldered to a ground plane pour for proper thermal and electrical connection. The low 0.90 mm profile suits dense mezzanine cards or blade assemblies where height is constrained.
