ADC12DJ2700EVM: Set up for DC coupled Input

Part Number: ADC12DJ2700EVM
Other Parts Discussed in Thread: ADC12DJ2700

Hello team,

Customer needs to evaluate ADC12DJ2700 for their application with a DC coupled input. I see the EVM has a transformer and supports 500kHz-9GHz inputs. Do we have a recommended setup for DC coupled signals?

Thanks

On the EVM, the customer would install R180, R179, R151, and R162, and remove R1, R4, R6, and R9. This would allow them to bring in a differential DC coupled signal on SMA J1 and J3 for channel A, and SMA J4 and J6 for channel B. The board schematic is attached for reference.

Regards,

Jim
