DS32kHz
32.768kHz Temperature-Compensated
Crystal Oscillator
GENERAL DESCRIPTION
FEATURES
The DS32kHz is a temperature-compensated
crystal oscillator (TCXO) with an output
frequency of 32.768kHz. This device addresses
applications requiring better timekeeping
accuracy, and can be used to drive the X1 input
of most Dallas Semiconductor real-time clocks
(RTCs), chipsets, and other ICs containing
RTCs. This device is available in commercial
(DS32kHz) and industrial (DS32kHz-N)
temperature versions.

Limits at -40°C are guaranteed by design and are not production tested.
All voltages are referenced to ground.
VBAT must be no greater than 3.5V when the device is used in the dual-supply operating modes.
Typical values are at +25°C and 5.0V VCC, 3.0 VBAT, unless otherwise indicated.
These parameters are measured under no output load conditions.
This current is the active-mode current sourced from the backup supply/battery.
A temperature conversion lasts 122ms (typ) and occurs on power-up and then once every 64 seconds.
