I see that the ADF7024 has an integrated temperature sensor. How do I use this sensor?
The integrated temperature sensor on the ADF7024 has an operating range between −40°C and +85°C. To enable readback of the temperature sensor in PHY_OFF, PHY_ON, or PHY_TX, the following registers must be set:
1. Set POWERDOWN_RX (Address 0x324) = 0x10 to enable the ADC.
2. Set POWERDOWN_AUX (Address 0x325) = 0x02 to enable the temperature sensor.
3. Set ADC_CONFIG_LOW (Address 0x359) = 0x08 to set the ADC input to the temperature sensor.
The temperature is determined from the ADC readback value using the following formula:
Temperature (°C) = 0.9474 × (ADC_READBACK[7:0] – CalibrationValue[7:0]) + TCALIBRATION
The calibration value[7:0] is determined via an ADC readback at a single known temperature, TCALIBRATION.
