Other Parts Discussed in Thread: ADC14X250
Hello,
I am trying to connect the SERDES output of ADC14x250 to SMA.
I am using an evaluation board AD14x250EVM where the SERDES outputs, SO+ and SO- (pins 19 and 20), are routed to FMC mezzanine connector. Hence I am using a FMC breakout board https://www.kayainstruments.com/fmc-prototype-board/ or https://hitechglobal.us/index.php?route=product/product&path=18&product_id=210 to convert the high speed signals to SMA.
The SERDES output is a source with 100ohms impedance that demands for a 100 ohm transmission lines and pcb traces, but SMAs are 50ohm impedance connections. So wont I have impedance mismatch? But I do observe that SMAs are used as standard high speed connection mediums, how do I make this connection?
Thank you in advance for your help.
