Product details

Four 50 MHz clocks from a MEMS core

The DSC400-1111Q0034KI1 is a MEMS-based XO (standard oscillator) that generates four identical 50 MHz LVCMOS outputs from a single silicon resonator — no quartz crystal needed. The MEMS die is inherently more resistant to shock and vibration than a quartz blank, which matters for equipment that ships assembled or sees mechanical stress in the field.

Industrial temperature and supply flexibility

The supply range spans 2.25 V to 3.6 V, covering both 2.5 V and 3.3 V rails directly — no extra regulator or level shifter for the oscillator core.

Enable/Disable function and package footprint

An Enable/Disable pin lets the system gate the outputs for power saving or test modes without removing supply. The 20-VFQFN with exposed pad (5.00 mm × 3.20 mm body, 0.90 mm max height) requires a thermal via pattern under the pad for proper heat transfer — the datasheet layout recommendation should be followed to keep junction temperature within limits.

Active lifecycle — design-in ready

This part is suitable for new designs and production builds.

Frequently asked questions

How can I order the DSC400-1111Q0034KI1 or request a quote?

Submit an RFQ with your target quantity. The part is Active and available through our independent distribution channel — we confirm availability and current pricing at quote time. No stock-holding claim is made; each order is quoted to the BOM line.

How does the Enable/Disable function work on this oscillator?

The Enable/Disable pin gates all four LVCMOS outputs. When disabled, the outputs go to a high-impedance state, allowing the downstream logic to be clock-gated for power savings or test isolation without cycling the main supply.
