Product Description

Available over low frequency range of 32.0kHz~30.0MHz, the MCSO1ESW CMOS 2.5V oscillator features good frequency stability over extreme operating temperature range of -10 to +210°C.

The MCSO1ESW also features excellent shock and vibration resistance specifications, fast start up time of 5ms, and relatively low current consumption for such a robust component.

This oscillator also has optional enable/disable tristate functionality, and features SAC (Sn/Ag/Cu) tinned pad terminations, ideal for material-sensitive applications and manufacturing processes.
