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 may 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 and industrial temperature versions, DS32kHz
and DS32kHz-N respectively.
The DS32kHz requires four pins for operation: V
3 for connection schemes. Power is applied via V
output in the absence of power. The output is accurate to ±7.5 ppm (±4 min/yr) from -40°C to +85°C and
±2 ppm (±1 min/yr) from 0°C to 40°C.
