Description

The STCL132K silicon oscillator devices are reliable, easy to use, 5-pin low-cost silicon oscillators

developed primarily for microprocessor clock applications, display drivers or other system applications

where tighter clock accuracy is not critical. Compared to crystal oscillators, silicon oscillators offer the

advantages of faster startup, smaller size and improved immunity to shock, vibration and EMI.

The STCL132K silicon oscillator devices are equipped with chip enable input, offering an easy way to

stop microprocessor clocking during a power saving mode while at the same time significantly reducing

the oscillator current consumption.
