Product details

The DSC1123DI2-187.5000T is a MEMS-based XO delivering a 187.5 MHz LVDS clock from a 2.25 V to 3.63 V supply rail. The 32 mA max supply current (22 mA disabled) is a fixed overhead — no load-capacitance tuning or drive-level adjustment needed, unlike a quartz oscillator.

AEC-Q100 qualification and package fit

The 6-SMD, No Lead package (2.50 mm x 2.00 mm, 0.90 mm seated height) is a standard MEMS oscillator footprint; the board layout matches the common 6-pin ceramic or plastic package outline.

MEMS vs quartz — what changes on the board

A MEMS oscillator replaces the quartz crystal plus load capacitors and inverter with a single IC. The DSC1123DI2-187.5000T is a direct drop-in for a standard 6-pin LVDS oscillator footprint — no external feedback network or tuning capacitors. The ±25 ppm stability includes the MEMS resonator's aging and temperature drift, so the timing budget is set by the oscillator alone, not the board parasitics.

Frequently asked questions

Can the DSC1123DI2-187.5000T replace a quartz oscillator in my design?

Yes, if the board expects a 6-pin LVDS oscillator with Enable/Disable. The MEMS device does not require external load capacitors or a feedback resistor — the oscillator is self-contained. Verify the supply voltage range (2.25 V to 3.63 V) and the output type (LVDS) match your clock receiver. The ±25 ppm stability is comparable to a standard quartz XO.

Is the DSC1123DI2-187.5000T compatible with a 2.5 V supply?

Yes. The supply voltage range is 2.25 V to 3.63 V, so 2.5 V is within the operating window. The oscillator's LVDS output swing scales with the supply, but the differential swing at 2.5 V still meets the LVDS receiver threshold — no level translation needed.
