Product details

Quad-output MEMS oscillator for dense timing trees

The DSC400-1111Q0084KI2T packs four independent LVCMOS clock outputs (33.33333 MHz, 50 MHz, 125 MHz, 100 MHz) into a single 20-VFQFN package, replacing up to four discrete XOs and freeing board space on multi-rail designs.

Supply voltage and frequency stability simplify rail planning

The 2.25V to 3.6V supply range covers both 2.5V and 3.3V rails without an intermediate regulator — a single LDO can feed the oscillator and the downstream logic. Frequency stability of ±25 ppm across temperature and supply variation keeps the clock edges within tight timing budgets for 100 MHz+ serial interfaces and high-speed ADCs.

Active lifecycle supports volume procurement and new designs

The part can be designed in today and sourced for production without lifecycle risk.

Frequently asked questions

What are the four output frequencies of the DSC400-1111Q0084KI2T?

The oscillator provides four LVCMOS outputs: 33.33333 MHz, 50 MHz, 125 MHz, and 100 MHz.

What supply voltage range does the DSC400-1111Q0084KI2T accept?

It operates from 2.25V to 3.6V, covering both 2.5V and 3.3V rails commonly used in mixed-voltage systems.

Is the DSC400-1111Q0084KI2T suitable for outdoor or industrial environments?

Yes, the -40°C to 85°C operating temperature range qualifies it for outdoor telecom, factory automation, and under-hood electronics.

Can the DSC400-1111Q0084KI2T replace a set of discrete oscillators?

Yes, its quad-output design replaces up to four single-output XOs, reducing BOM count and board area. The 20-VFQFN package with exposed pad requires a thermal pad on the PCB for proper heat dissipation.
