18.75 MHz MEMS clock with standby shutdown
The DSC1101NI5-018.7500: The ±10 ppm absolute pull range covers supply ripple and temperature drift, keeping the output within tight frequency tolerance for 10/100 Ethernet PHY reference or UART baud-rate generation.
Industrial temp and wide-rail flexibility
The 2.25 V–3.6 V supply tolerance means the same BOM line serves both 2.5 V and 3.3 V logic domains without an intermediate regulator — the oscillator powers directly from the rail.
Standby current and power-down function
When the standby (power-down) pin is asserted, the oscillator draws 95 µA max — low enough to leave it powered on a battery-backed rail during sleep, avoiding a start-up latency penalty on wake. Active-mode supply is 35 mA max at 18.75 MHz, typical for a MEMS XO driving a CMOS load — the power budget for the clock tree is predictable.
Confirm the 6-VDFN footprint (7.00 mm × 5.00 mm, 0.90 mm seated height) matches the board layout before committing.
