What the AEC-Q100 grade means for this MEMS oscillator
The DSC8123CI2T: The MEMS resonator is the key differentiator from quartz XOs — no crystal blank to crack under vibration or thermal shock. That matters in an automotive environment where the board sees constant mechanical stress.
LVDS output and programmable frequency — fit for high-speed serial links
LVDS output delivers the differential swing needed for clocking SerDes, Ethernet PHYs, or FPGAs over a 10 MHz to 460 MHz range. The 32 mA max supply current is the full-load draw at the highest frequency — the actual draw scales with frequency and output load. This is a blank programmable part (user programs the frequency before reflow), not a fixed-frequency oscillator.
