250 MHz LVDS MEMS XO — clocking the high-speed bus
The DSC1103AI2-250.0000: The MEMS resonator replaces the quartz crystal, eliminating crystal aging drift — useful for outdoor telecom cabinets and factory-floor vibration environments.
Supply voltage flexibility and power budget
The 2.25V to 3.63V supply range covers both 2.5V and 3.3V rails — no separate LDO needed when the core logic runs 2.5V and the I/O bank runs 3.3V; the oscillator follows whichever rail is cleaner. Maximum supply current is 32 mA while oscillating; in standby mode the disable function drops draw to 95 µA max — the pin is active-low, so pulling it high enables the output, and a simple GPIO or pull-up resistor controls the power state.
