Description

CANADUINO® High Precision 1Hz Clock Generator offers a time base with 1Hz and 1024Hz outputs.

The operation voltage (and output level) is 3-5V and the maximum output current is +/- 24mA (source/sink).

The module guarantees a tolerance of no more than 3.8ppm @ -10…+60 C, and a maximum tolerance of 5ppm within its operating temperature range of -40…+85 C.

In other words, a clock that is synchronized using the CANADUINO® High Precision 1Hz Clock Generator, has a maximum drift of 2 minutes per year @ -10…+60 C.

We designed this module with discrete or analog DIY clock projects in mind, as an alternative to microcontroller based clocks with RTC chips. The 1kHz (1024Hz exactly) output can be used for an alarm sound, for example.

The tiny module measures only about 10*11mm.

Straight pin header included.

    royneville (verified owner) –

    Had originally planned to use this to pull in the accuracy of a DS3231 based RTC module – before I could get around to that project, I found myself with a space limited application – no room for an RTC module. So I connected the 1Hz o/p of the generator to the Arduino Nano interrupt pin, and with a handful of lines of code, I had hours and minutes up and running, which is all I needed. Maximum drift of 2 minutes per year ? Amazing. As is usually the case with Universal Solder products – much bang for the buck.
