    Hello Eggsy,

    Here is my review feedback:

    I do not see any AC-Coupling capacitors or termination resistors connected to the Input pins as recommended in the datahseet.
    I do not see any PoC network connected to the Input pins.
    I dont see any pull-up resistor or biasing of the I2C pins.
    Please use VDD_1.8V to supply PDB pin. Also it is recommended to use 10Kohm + 10uF as shown in figure 40 in page 147.
    please follow datasheet page 5 for the correct number and values of decoupling capacitors at each pin.
