I've recently purchased a LMK04906 Evaluation Board (2011-12-06 v1.0). However, I'm unable to operate the board and generate an output clock despite my best efforts.
I've followed the User's Guide closely with my board and the program CodeLoader (program version: 4.9.0; part file version: 2013-08-19, v1.2). As soon as a 5.0 V power supply is connected to the Vcc input on the board, I observe a 25 MHz square wave at CLKout3 and CLKout3* and a 95 MHz square wave at CLKout4 and CLKout4*. The rest of the outputs have no signal. I then connect a 125 MHz square wave to the FBCLKin*/CLKin1* input on the board. After repeating the User's Guide's steps, I'm unable to change any of the signals I see from the outputs. I would appreciate any and all help in getting my eval board up and running as soon as possible.
Please note that the LED 'D4' was red, as expected, during my tests. Also note that I'm using your USB2ANY adapter to connect the eval board to my PC running Windows 7. The signals were observed using an Agilent Technologies InfiniiVision MSO07104 Oscilloscope with a 50 Ohm impedance. The 125 MHz input clock was generated using a Picosecond Pulse Labs Model 12020 1.6 GHz Pulse/Pattern Generator which has a 50 Ohm impedance. I have taken photos, screenshots, and scope traces detailing what I've done and observed. This supporting documentation has been compiled into a PDF which is attached to this post.
Steps to recreate the problem:
1) Connect 5.0 V from power supply to Vcc input on eval board
2) Connect 125 MHz square wave from pulse generator to FBCLKin*/CLKin1* input on eval board
3) Open "CodeLoader 4" program on PC running Windows 7
4) In the "Port Setup" tab, select "USB" radio button in "Communication Mode" section
5) In the "Pin Configuration" section, set the Clock Bit to 8, Data bit to 4, LE Bit to 2, SYNC to 1, Status_CLKin0 to 9, Status_CLKin1 to 3, and TRIGGER to 10
6) In the menu bar, select "Select device" > "Clock Conditioners" > "LMK0406B" (and press Control-L)
7) In the menu bar, select “Mode” > “125 MHz CLKin1, 25 MHz VCXO” (and press Control-L)
8) In "Clock Outputs" tab, select "Powerdown" checkbox for CLKout1, deselect "Powerdown" checkbox for CLKout2, and set Clock Output to "LVCMOS (Norm/Norm)" (and press Control-L)
9) In "Bits/Pins" tab, set CLKin1_BUF_TYPE to "MOS" in "CLKin" section (and press Control-L)
