The base resonator is a silicon MEMS structure, which means no quartz crystal to fracture under shock or vibration, and no aging drift that shifts the frequency over years. On a repair bench, when a board comes in dead from a dropped system, a quartz can is often the first suspect; this part doesn't have that failure mode. ## 84.4032 MHz at ±20 ppm — timing budget for high-speed links That stability holds the timing budget for 1 GbE or a 10 GbE SERDES reference clock without stepping up to a TCXO. The 84.4032 MHz value is non-standard — it matches a specific PHY or FPGA reference, not a common 25/50/100 MHz — so confirm your BOM's target frequency before ordering. The supply voltage range is 2.25 V to 3.6 V, which covers both 2.5 V and 3.3 V rails without an external LDO. On a mixed-voltage board, one oscillator BOM line serves both domains — no second variant needed. The product status is Active. No NRND flag, no EOL notice. For a production line or a repair stockroom, this part isn't going away — you can commit the BOM position without a lifetime-buy trigger.","metaTitle":"DSC1121AI3-084.4032 MEMS XO 84.4032 MHz CMOS ±20 ppm -40°C","metaDescription":"DSC1121AI3-084.4032 Microchip MEMS XO, 84.4032 MHz CMOS output, ±20 ppm stability, 2.25-3.6 V supply, -40 to 85°C, 6-VDFN.
