GENERAL DESCRIPTION
The DS32kHz is a temperature-compensated crystal
oscillator (TCXO) with an output frequency of
32.768kHz.
requiring better timekeeping accuracy and can be
used
Semiconductor real-time clocks (RTCs), chipsets, and
other ICs containing RTCs. This device is available in
commercial (DS32kHz) and industrial (DS32kHz-N)
temperature versions.

... OPERATION The DS32kHz module contains a crystal and an IC. While powered, the DS32kHz peridocially measures the temperature and adjusts the crystal load to compensate. The DS32kHz is designed to operate in two modes. In the dual-supply mode, a comparator circuit, powered by V monitors the relationship between the the device switches over to V ...

... RTC as well. Figure 5 shows one circuit that BAT can be used to reduce the current consumption of a DS32kHz and an RTC. The values of R1 and C1 may vary depending on the RTC used. However, values of 1.0MW and 100pF are recommended as a starting point used to shift the input waveform to the proper level ...
