Product details

Four-output MEMS oscillator for clock-tree consolidation

The DSC400-1133Q0113KI1 packs four independent clock outputs into a single 5.00 mm x 3.20 mm 20-VFQFN package — 100 MHz, 156.25 MHz, 125 MHz (two copies), and 25 MHz — replacing up to four discrete oscillators and their associated decoupling capacitors. Outputs are configurable as LVCMOS or LVDS per the DSC400 family architecture, letting a single device feed both a SerDes reference (LVDS) and a logic clock (LVCMOS) without a level translator.

Supply flexibility and enable/disable control

Operates from 2.25 V to 3.6 V, covering both 2.5 V and 3.3 V rails without an external regulator — the wide input range absorbs rail tolerance in mixed-voltage systems.

Frequently asked questions

Is DSC400-1133Q0113KI1 compatible with a 2.5V supply?

Yes. The supply range is 2.25 V to 3.6 V, so a 2.5 V rail is well within tolerance — no external regulator needed.

Can I replace DSC400-1133Q0113KI1 with a standard crystal oscillator?

Not as a drop-in. A standard crystal oscillator provides a single output; this MEMS device delivers four independent frequencies (100/156.25/125/25 MHz) from one package. Replacing it with discrete oscillators would require four separate parts and more board area.

What is the output type of DSC400-1133Q0113KI1?

The outputs are LVCMOS and LVDS, configurable per the DSC400 family. The 100 MHz and 156.25 MHz outputs are typically LVDS for high-speed SerDes clocks; the 125 MHz and 25 MHz outputs are LVCMOS for logic and control.
