Pin Function
1.2V analog VDD for PLL input power supply from VDDCO (pin24) through external Ferrite
bead and capacitor.
Analog ground
25MHz crystal or oscillator clock connection.
Pins (X1, X2) connect to a crystal. If an oscillator is used, X1 connects to a 3.3V tolerant
oscillator and X2 is a no connect.
Note: Clock requirement is 50ppm for either crystal or oscillator.
Reset Not
Hardware reset pin (active Low). This reset input is required minimum of 10ms low after
stable supply voltage 3.3V.
