TLK10034 Evaluation Module Input and Output Interfaces

Other Parts Discussed in Thread: TLK10034

Hi,

I am planning to use the TLK10034 Evaluation Module (EVM) for providing multiple high-speed serial inputs to a transmitter IC. I see that the high-speed Tx outputs for channels A & B in the evaluation module come out in SFP modules. Is it possible to remove those modules and bring out these outputs to SMA connectors instead? Is it possible to specify this when purchasing the EVM? Otherwise one needs to use SFP to SMA adapter and that might cause difference in the characteristics of channel A &B outputs compared to channels C & D. I am asking because my application requires all four channels to transmit (random) data that are synchronized and have identical frequency characteristics.

Also, can the low-speed inputs to the EVM be interfaced with PCI Express?

Thanks,

Anandaroop

    Hi Anandaroop,

    The TLK10034 EVM is not configurable or have any additional options. It was designed to allow customers to evaluate the performance characteristics of the TLK10034 in both electrical backplane and optical applications, but not intended to be used as the final application board itself. The product line only wanted to design and maintain a single EVM and so both electrical and optical connections had to be placed on the same EVM. This was decided to be good enough for a customer to determine the quality of the device and determine whether or not to invest the time and money into designing our part into their final application.

    You are right that you would need to use SFP to SMA breakout boards to get electrical versions of channels A and B out on SMA connectors. You are also correct that this will cause slightly different characteristics due to the additional loss of the SFP to SMA adapters.
