HSMC-ADC Bridge and ADS42LB69 EVM compatibility

Other Parts Discussed in Thread: ADS42LB69, ADS42LB49

I need to interconnect ADS42LB69 EVM with Arria V FPGA development kit ( from Altera. Arria V FPGA kit has HSMC connector on it. I need to use both the ADC channels on the EVM. 

There is an interposer card HSMC-ADC Bridge. But this card seems to be compatible only with ADS42LB49 EVM (Only one ADC channel can be used as suggested in another thread on the forum). 

When this interposer card is used with the ADS42LB69 EVM, LS-bit of one channel and MS-bit of other channel are grounded on the ADC connector of the interposer card.

Kindly suggested any other interposer card from TI for interfacing ADS42LB69 EVM with Arria V FPGA kit.

    TI does not offer another adapter board that would work for this interface. One option is to modify this board to remove these ground connections. The pcb design files can be downloaded from the TI website.
