14.7456 MHz MEMS oscillator with ±10 ppm stability
The DSC1101CL5-014.7456 is a MEMS-based XO (Standard) oscillator from Microchip's DSC1101 series, delivering a 14.7456 MHz CMOS output with ±10 ppm frequency stability across its full -40°C to 105°C industrial temperature range. The MEMS resonator replaces a quartz crystal, offering better shock and vibration tolerance — useful for motor drives, outdoor telecom, and engine-bay electronics where a quartz crystal might drift or fail under mechanical stress.
Standby mode and supply voltage flexibility
A Standby (Power Down) function on pin 1 drops the supply current to 95 µA max — the oscillator stops and the output goes high-impedance, letting the system clock tree be gated without an external load switch. The supply voltage range of 2.25V to 3.6V covers common 2.5V and 3.3V rails, and the 35 mA max active current is typical for a 14.7456 MHz CMOS output driving a moderate capacitive load.
