DESCRIPTION
The DS32KHz is a temperature compensated crystal oscillator (TCXO) with an output frequency of
32.768 kHz. This device addresses applications requiring better timekeeping accuracy and may be used to
drive the X1 input of most Dallas Semiconductor Real Time Clocks (RTC’s), chipsets and other IC’s
containing RTC’s. This device is available in commercial and industrial temperature versions, DS32KHz
and DS32kHz–N respectively.
The DS32KHz requires four pins for operation: VCC, GND, VBAT and 32 kHz OUT. See Figures 1, 2 and
3 for connection schemes. Power is applied via VCC and GND, while VBAT is used to maintain the 32 kHz
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.
