DS32kHz

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.
