Product details

100 MHz LVDS clock for industrial timing

The DSC1123AL5-100.0000 is a MEMS-based XO delivering a 100 MHz LVDS output with ±10 ppm frequency stability across the full -40 to 105°C industrial range — tight enough for 1 GbE reference clocks or FPGA transceiver links without an external PLL cleanup. Supply voltage spans 2.25V to 3.63V, so it runs from a 2.5V or 3.3V rail without a separate regulator; the Enable/Disable function lets the system shut down the oscillator for low-power sleep modes.

6-SMD, No Lead Exposed Pad package measuring 7.00mm x 5.00mm with a seated height of 0.90mm.

Frequently asked questions

Is the DSC1123AL5-100.0000 a MEMS oscillator?

Yes, the base resonator is MEMS, not quartz. This gives better shock and vibration tolerance compared to a crystal-based XO.

What is the difference between the DSC1123AL5-100.0000 and the DSC1123AM5-100.0000?

Both are 100 MHz LVDS MEMS oscillators in the DSC1123 family. The difference is in the package or stability option — the 'AL5' suffix indicates ±10 ppm stability and the 7.00mm x 5.00mm 6-SMD package. The 'AM5' variant uses a different package size or stability grade; confirm the exact suffix against your BOM before substituting.

Is the DSC1123AL5-100.0000 RoHS compliant?

The evidence does not list a RoHS compliance statement. Most Microchip MEMS oscillators in the DSC1123 series are RoHS-compliant, but verify against the latest datasheet or the manufacturer's declaration for your specific date code.
