Product details

50 MHz MEMS XO with LVDS output – AEC-Q100 qualified

Supply voltage and package – board-fit checklist

Runs on a 2.25 V to 3.63 V supply rail – compatible with both 2.5 V and 3.3 V logic domains without an external regulator. Housed in a 6-SMD, No Lead Exposed Pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm – the exposed pad aids thermal conduction to the PCB ground plane. Surface-mount assembly; the 0.90 mm profile fits tight mezzanine stacks or card-edge designs where height is constrained.

Frequently asked questions

Is DSC1123AL2-050.0000 AEC-Q100 qualified?

Yes – the DSC1123AL2-050.0000 carries an AEC-Q100 rating, making it suitable for automotive applications requiring the temperature and reliability stress screening that grade implies.

What is the output logic of DSC1123AL2-050.0000?

The output is LVDS – a differential low-voltage signal that keeps jitter low over long PCB traces or cables, common in high-speed clock distribution for ADCs, FPGAs, and SerDes interfaces.

Can DSC1123AL2-050.0000 replace a standard quartz oscillator?

Yes, in most cases – the MEMS resonator is a drop-in replacement for quartz XOs in the same 7.0 mm x 5.0 mm footprint, with the advantage of better shock and vibration tolerance. Confirm the supply voltage (2.25 V to 3.63 V) and output type (LVDS) match your existing circuit.
