Other Parts Discussed in Thread: USB2ANY-UWIRE, USB2ANY
I am having trouble getting started with the LMK04906BEVAL board. On page 6 of the manual is a very nice procedure to get the board up and running. I am using a BK Precision 1760A supply to provide 5V to the VCC SMA and an HP 4648C Signal Generator to provide the 125MHz sine wave into the FBCLKin*/CLKin1* SMA. I have confirmed I am getting both 3.3V at the chip and the 125MHz after C16. I have directly connected the USB2ANY-UWIRE (HPA665) device, with the latest firmware on it, to the UWIRE header on the evaluation board. I have tried programming the device repeatedly with the default setting (125MHz CLK1 in, 25 MHz VCXO) and have been unsuccessful at getting the lock status LED to light up. I've tried using the Codeloader4 software and the TCIS Pro software on two different PCs, one running Win10 the other Win7).
I have begun probing the CLKinX_IND test points to see which clock is getting selected, and, after configuring the default settings from above, the readings are as follows 0V, 1.3V, and 2.2V for CLIKin0 - CLIKin2 respectively. I've also probed the vias off of the UWIRE header for CLKSel1 and CLKSel0 which read 3V, 0V, respectively. According to the board's manual, that means it is selecting CLKin2, which is consistent with the test point readings... I've tried to change those settings using the TCIS Pro software, but I am always getting some value on CLKSel1.
I should also mention that the manual has an Appendix I where it lists two options for connecting to the board. Option 2 is for the USB2ANY device and it shows a small jumper board in line with the connection. Nowhere else in the manual does it mention this board but it comes up again on the TCIS Pro software under the 'USB Communications/Interface.' I've received email correspondence that this board is not needed... Can this be confirmed?
The only indicator I've seen that it's alive is the Holdoff LED has turned one twice... and only ever after a hard reset... So I could really use some help. I am sure I am doing something wrong and I hope it is something obvious.
