Product details

Four LVPECL clocks from one MEMS die

The DSC400-2222Q0105KI1T packs four LVPECL output frequencies — 200 MHz, 156.25 MHz, 125 MHz, and 100 MHz — into a single 20-VFQFN package with exposed pad. That replaces four discrete quartz oscillators and their associated bypass caps, freeing board area on a dense clock tree.

Supply flexibility and output control

Supply voltage spans 2.25 V to 3.6 V — the same BOM position works on a 2.5 V or 3.3 V rail without a separate regulator.

Active lifecycle, tape-and-reel delivery

Product status is Active — no EOL notice, no last-time-buy window. Store the reels dry: the 20-VFQFN exposed pad is moisture-sensitive, and the reel label carries the MSL level.

Frequently asked questions

Can DSC400-2222Q0105KI1T replace a standard 200 MHz LVPECL quartz oscillator?

Functionally yes — it outputs LVPECL at 200 MHz with ±50 ppm stability. The MEMS resonator is more shock-tolerant than quartz. The pinout and footprint of the 20-VFQFN package differ from a standard 7×5 mm or 5×3.2 mm quartz oscillator; confirm the PCB land pattern against the datasheet before committing.

Is DSC400-2222Q0105KI1T compatible with a 2.5 V supply?

Yes. The supply voltage range is 2.25 V to 3.6 V, so a 2.5 V rail is within spec. No external regulator is needed between the rail and the VDD pin.
