The temperature is monitored at the package back-side interface (TCase) as shown below. The system maximum temperature must be adjusted in order to guarantee that TCase remains below than the maximum value specified in the next table. So, the system PCB must be designed to comply with this requirement.

CHC2442-QPG 24GHz ISM SENSOR SPI The digital input should use standard 4-wires synchronous serial peripheral interface (SPI) with data read and write capabilities. The SPI has hardwired Power-On Reset, such that the output bits for Control Bus will be set to default state (low power mode) after turning on 3.3V supply. Data transmission is enabled by negative edge of CS (Chip Select) and serial data input (SI) are then read at the rising edge of CLK (SPI Clock). The timing diagram in the next picture describes the principle of the SPI timing and handling between shift and storage register.
