32.768kHz Temperature-Compensated
Crystal Oscillator
www.maxim-ic.com
GENERAL DESCRIPTION
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.
