GENERAL DESCRIPTION
The DS32kHz is a temperature-compensated
crystal
oscillator
(TCXO)
with
frequency of 32.768kHz. This device addresses
applications
requiring
better
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
temperature versions.
APPLICATIONS
GPS Receivers
Telematics
Network Timing and Synchronization in Servers,
Routers, Hubs, and Switches
Automatic Power Meters
