50 MHz MEMS clock for supply-constrained boards
The DSC1101AE1-050.0000 is a MEMS-based XO (Standard) that outputs a 50 MHz CMOS clock from a 6-SMD No Lead package, drawing 35 mA max from a supply rail that accepts 2.25V to 3.6V. Because the base resonator is MEMS rather than quartz, the oscillator starts faster and withstands higher shock and vibration — a practical advantage in portable equipment and fan-cooled systems where quartz can fail from mechanical resonance.
Standby function and current budget
The standby (power-down) function drops supply current from 35 mA to 95 µA max, letting the system architect gate the clock during sleep modes without a separate load switch. The ±50 ppm frequency stability over -20°C to 70°C holds the timing margin for UART bit rates and Ethernet reference clocks without a temperature-compensation loop.
Active lifecycle and ordering
Microchip lists the DSC1101AE1-050.0000 as Active — no NRND or EOL flag, so volume production orders and new designs can proceed without a last-time-buy risk.
