FUNCTIONAL DESCRIPTION
The DS32kHz is a temperature-compensated crystal oscillator (TCXO) that outputs a 32,768Hz square wave.
While the DS32kHz is powered by either supply input, the device measures the temperature every 64 seconds and
adjusts the output frequency. The device requires four pins for operation: V

32kHz output in the absence of power. Once every 64 seconds, the DS32kHz measures the temperature and
adjusts the output frequency. The output is accurate to ±2ppm (±1 min/yr) from 0°C to +40°C and to ±7.5ppm
(±4 min/year) from -40°C to 0°C and from +40°C to +85°C.
