RX8900CE High Stability, Low Power RTC

Designed for precision time keeping, Epson’s RX8900CE uses Digitally Temperature-Compensated Crystal
Oscillator (DTCXO) technology to achieve ±3.4 or ±5 ppm accuracy over temperature, equivalent to ±9 or ±13 seconds per month. Compared to RTCs integrated into microcontrollers (MCUs), Epson’s RX8900CE includes an
integrated crystal, is lower power, and is far more accurate.
