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.

APPLICATIONS

GPS Receivers

Telematics

Network Timing and Synchronization in Servers,

Routers, Hubs, and Switches

Automatic Power Meters
