LVDS differential swing keeps the edge rates clean across a short PCB trace; the 32 mA max supply draw is the total current budget for the oscillator itself, not counting the line termination. ## Supply flexibility and frequency hold-in The 2.25V–3.63V supply range lets this oscillator run off a 2.5V or 3.3V rail without a dedicated LDO — useful when the FPGA bank voltage is already set. The ±50 ppm absolute pull range is the total frequency variation over voltage, temperature, and aging; a system PLL that needs better than 50 ppm total drift must budget the oscillator's APR into its hold-in calculation. ## Active production — no end-of-life watch","metaTitle":"DSC1123AM1-287.0000 – Microchip 287 MHz LVDS MEMS XO –","metaDescription":"DSC1123AM1-287.0000: Microchip DSC1123 series, 287 MHz LVDS output, XO (Standard) with MEMS resonator. 2.25V–3.63V supply, ±50 ppm APR.
