The DSC8123DI2: The ±25 ppm total frequency stability covers temperature, supply, and aging drift — tight enough for most automotive Ethernet and sensor clock domains without external trimming.
Supply current and enable/disable function
Max supply current is 32 mA across the full frequency range — the LVDS output stage dominates the draw; the MEMS resonator itself consumes under 1 mA. The blank-programmable variant means the frequency is set at the distributor or factory — not field-changeable — so order the pre-programmed part number that matches your target frequency.
