The RV-8063-C7 has low current consumption of just 190nA typical and is operable over wide voltage range of 0.9V to 5.5V with time accuracy of ±20ppm @ 25°C, making it an ideal all-in-one solution for projects requiring an SPI-bus interface. It provides clock output frequencies of 32.768kHz and 1Hz and also features a miniature surface
RX8804 DTCXO RTC WITH PRECISE TIME KEEPING, HIGHER ACCURACY OVER TEMPERATURE AND LOW POWER
Designed for precision time keeping, Epson’s RX8804 uses Digitally Temperature-Compensated Crystal Oscillator (DTCXO) technology to achieve ±3.4 or ±8 ppm accuracy over temperature of -40 to +85 °C or -40 to +105 °C respectively, equivalent to 9 or 20 seconds per month. This high accuracy is essential for precise time keeping, as required by eMeters,
