Product details

MEMS oscillator with four independent clock outputs

Output frequencies are factory-configured: three lanes at 25MHz and a fourth lane selectable between 100MHz and 156.25MHz, supporting HCSL or LVCMOS logic levels. Frequency stability is rated at ±25ppm across the full -40°C to 85°C industrial temperature range, with a supply voltage tolerance of 2.25V to 3.6V.

Package, footprint, and board-level integration

Housed in a 20-VFQFN with exposed pad, measuring 5.00mm x 3.20mm with a seated height of 0.90mm — the thermal pad must be soldered to a PCB ground plane for rated heat dissipation and mechanical stability.

Frequently asked questions

What are the output options for DSC400-4111Q0112KI2T?

The device provides four outputs: three fixed at 25MHz and a fourth lane configurable to 100MHz or 156.25MHz. Output logic is selectable between HCSL and LVCMOS levels.

Is DSC400-4111Q0112KI2T a direct replacement for a standard quartz crystal oscillator?

No — this is a MEMS-based XO, not a quartz resonator. It generates multiple clock frequencies from a single silicon die, whereas a quartz oscillator typically provides one fixed frequency. The pinout and supply voltage (2.25V–3.6V) differ from common 3.3V or 5V quartz oscillators; verify compatibility with the target socket before substitution.
