Product Description

The GTXO-94J is a tight stability 32.768kHz 2.5V temperature compensated oscillator which provides a very low power solution, consuming typically just 1.05µA. This makes the GTXO-94J ideal for use as an RTC reference or within data loggers, smart meters and other portable devices which depend on battery supplies. The tight stability of the GTXO-94J, just ±5ppm, also means that this product is suitable for applications which require tight stability output at 32.768kHz.
