Product details

Quad-output MEMS XO with HCSL and LVCMOS lanes

Three lanes are fixed at 25 MHz each, supporting either HCSL or LVCMOS logic levels; the fourth lane is factory-programmed to 100 MHz or 156.25 MHz, making it a single-device clock source for a multi-rail FPGA or SoC clock tree. For a design that already uses the DSC400 family, this order code locks in a specific frequency plan — confirm the four output frequencies match your BOM before committing.

The 2.25V–3.6V supply range means this oscillator runs directly off a 2.5V or 3.3V rail without an intermediate LDO.

Active production, Tape & Reel packaging

The 0.90 mm height and 5.00 mm × 3.20 mm footprint fit within typical mezzanine card and module height budgets.

Frequently asked questions

Is DSC400-4111Q0112KE1T compatible with a 2.5V supply?

Yes. The supply range is 2.25V–3.6V, so a 2.5V rail is well within the operating window. No external regulator is needed between the rail and the VDD pin.

Does DSC400-4111Q0112KE1T support an enable/disable function?

Yes, the function is listed as Enable/Disable. A logic-level on the enable pin gates all four outputs, which allows the system to shut down the clock tree during low-power modes without a separate clock buffer.
