Product details

MEMS oscillator for general-purpose clocking

The DSC1121AE1-004.0000T is a MEMS-based XO (Standard) oscillator from Microchip Technology, delivering a fixed 4 MHz CMOS output with ±50 ppm frequency stability across its -20 to +70 °C commercial temperature range. The Enable/Disable function on pin 1 gates the output — pulling it low stops the clock and drops supply current to 22 mA max, useful for power-down modes in battery-powered equipment.

Sourced through independent distribution; quoted to order against the BOM quantity.
