The jp45,jp46,jp49,jp50,jp51,jp52,jp53 on the board determine the value of IS and ND. In the doc,there are there operating frequencies as follow: IS ND 55 MHz 10 0 1 0 1 1 46 MHz 10 0 1 0 0 1 36 MHz 10 0 0 1 1 1 But on the board all the jumper’s value is 1. But my board works successfully! I am bewildered by this .Can somebody explain it for me?
just ignore it.I have overcome this problem
