Product details

432 MHz LVDS clock with AEC-Q100 grade

The DSC1123CI2-432.0000T is an active-production XO (Standard) from Microchip, delivering a 432 MHz LVDS output from a MEMS resonator. The LVDS differential pair keeps jitter low and common-mode noise rejection high on long traces or through connectors — useful for clocking a SerDes transceiver or an FPGA gigabit transceiver bank. It fits under-hood or cabin domains where the ambient hits -40°C to 85°C and vibration is a given.

Supply range and disable function

Supply voltage spans 2.25V to 3.63V — a single rail covers 2.5V and 3.3V logic families without a separate LDO.

6-SMD, No Lead package measuring 3.20mm x 2.50mm with a seated height of 0.90mm. Standard reflow profile for lead-free solder; no special bake unless the moisture-sensitive label says otherwise.

Frequently asked questions

What is the output type of the DSC1123CI2-432.0000T?

LVDS — a differential pair that delivers clean edges at 432 MHz with low EMI. The 100-ohm termination resistor goes across the receiver inputs, not to ground.

Is the DSC1123CI2-432.0000T AEC-Q100 qualified?

Yes, the part carries AEC-Q100 ratings, meaning it passed automotive-grade reliability testing. Suitable for under-hood and cabin electronic modules.

How does the DSC1123CI2-432.0000T compare to a standard quartz crystal oscillator?

It uses a MEMS resonator instead of a quartz crystal. MEMS oscillators typically offer faster startup, better shock/vibration tolerance, and smaller package size at the same frequency stability (±25 ppm,). The trade-off is that quartz can achieve tighter initial accuracy and lower phase noise in some designs — but at 432 MHz LVDS, the MEMS approach is the practical choice for automotive and industrial applications.
