AD9670EBZ error

Hi,

 

I recently started testing the AD9670 chip, and purchased a AD9670-EBZ and HSC-ADC-EVALCZ boards.  In my setup I have the two boards connected to two separate 6V/2A power supplies and the HSC-ADC-EVALCZ connected to the PC via usb.  The two eval boards are connected to each other, but when I open the SPIController application, I am getting alot of strange errors.  First - the chip ID that its reading back is "AD9246, 14bit 125MSPS" which doesn't match the chip that I am testing.  Second - when I try to initialize the chip with the AD9670_Initialization_v2.mgp file, it doesn't seem to do anything.  All my sample data captures from VisualAnalog have no data in them.  I can confirm that the FPGA on the HSC-ADC-EVALCZ is programmed as the DONE LED is turned on.  Have anyone ever seen this?
