Real Time Clock

A Real Time Clock (RTC) is an integrated circuit which keeps very accurate track of time and is used in a wide range of electronic equipment where time, day, month, year and an alarm function is required. IQDs range of Real Time Clocks includes a 32.768kHz crystal and a digital compensated TCXO. By incorporating the TCXO within the RTC it allows for a very tight stability, down to ±3.4ppm over an operating temperature range of –40 to 85°C.
