CDCE62005EVM: No device communication with GUI

Part Number: CDCE62005EVM
Other Parts Discussed in Thread: CDCE62005

Hello,

I believe I cannot get my computer to communicate successfully with the CDCE62005EVM's onboard TUSB3210 chip.

Following the evaluation module's setup instructions, I performed the following steps:


1) I installed the CDCE62005 EVM GUI (v1.4.8)and associated drivers successfully - module shows up in "My Devices" in 64-bit Windows 7.

2) When opening GUI I get "CDCE62005 detected - load register data from EVM?" popup but I get another popup after that with a ton of invalid register warnings. If I load default values it allows the GUI to open with all 3 "EVM Power", "USB Status" and "SPI Bus Status" indicators lit, but it seems that I still can't write to the EVM.

3) in "SPI Debug" menu, I get "00000001" for all register values when I press the "Read" button. The indicators showing "PLL Lock" and "DEV COMM" are not lit.

4) No devices are present when I try to open the "TUSB3x10 EEPROM Burner" utility (v2.2.0.0)

5) I have not seen any of the on-module "DEVICE COMM", "PLL LOCK" or "CD MODE" LEDs light up at any point while running the software, but the D26 LED on the backside of the board is lit (indicating 3.3V output on U2, I believe).

The board acts the same way whether powered by USB alone, or with an external 3.3V supply. Since the 3.3V regulator never gets enabled when powering from USB, the CDCE62005 never powers up. However, I do get a ~156MHz waveform from channel 0 when powered externally.

Am I missing something crucial during initialization and setting up the hardware improperly?

Thanks!
