T is the temperature in Kelvin.

R0 is the known resistance at calibration temperature T0.

B (beta) is the material constant.

The ADC reading of thermistors TS1 and TS2 can be monitored by the I2C interface. The ADC value can be calculated using the thermistor

resistance formula and the following:

PCB Layout Consideration

For optimum device performance and lowest output phase noise, IDT recommends that customers copy the reference layout used in the

P9027LP-R-EVK reference kit. More information and layout files can be found at http://www.idt.com/WP3W-RK.

Additional layout guidelines can be found in application note AN-933. Users are encouraged to read this document prior to starting a board

design.
