Trips and Tricks

External AD9361 reference clock via J1

An external Reference Clock can be supplied via J1. In order the switch the source the zynq-adrv9361-z7035.dtsi device tree needs to be modified. 

	clocks {
		xo_40mhz_fixed_clk: clock@0 {
			#clock-cells = <0>;
			compatible = "fixed-clock";
			clock-frequency = <40000000>;
			clock-output-names = "XO_40MHz";
		};

		ad9361_clkin: clock@1 {
			#clock-cells = <0>;
			compatible = "gpio-gate-clock";
			clocks = <&xo_40mhz_fixed_clk>;
			enable-gpios = <&gpio0 105 1>; /* Set to 1 for extern AD9361_CLK */
			clock-output-names = "ad9361_ext_refclk";
		};


Option:
    enable-gpios = <&gpio0 105 ACTIVE_LEVEL>;

    ACTIVE_LEVEL:
    0 (active high) use on-board XO
    1 (active low) use external clock via J1
  1. Update the clock-frequency property with the exact frequency of the external supplied clock.
  2. Set enable-gpios = <&gpio0 105 1>
  3. Rebuild and install your modified device tree on the target
