50 MHz MEMS XO with LVDS and AEC-Q100 qualification
The DSC1123CI2-050.0000 is a 50 MHz MEMS-based oscillator from Microchip's DSC1123 series, delivering an LVDS output — a differential signal pair that rejects common-mode noise on long board traces or cables, making it a clean clock source for high-speed serial interfaces like Ethernet PHYs or FPGAs that expect LVDS inputs.
Supply flexibility and enable/disable control
The supply range spans 2.25V to 3.63V, so it runs directly off a 2.5V or 3.3V rail without a separate regulator. At 3.3V, maximum supply current is 32 mA, and the disable function drops it to 22 mA — useful for power-gating a clock tree during system sleep modes. The Enable/Disable pin is a standard tri-state control: pulling it low puts the output into high-impedance, not just stopping oscillation, so multiple oscillators can share a bus without contention.
