Hello:
ADS5407 provides two copies of SYNCOUTP/N at pin (F1,F2) and (N9, P9), which we do not use in our design. So we are going to put a 100 ohm resistor externally as LVDS termination. My question is that each pair of (F1, F2) and (N9, P9) should have a 100 ohm respectively (that means there are total two 100 ohm resistors) or only one 100 ohm resistor is oaky for both (F1, F2) and (N9, P9)?
The description in serial interface portion of the data sheet (at page 36) says, to disable this SYNC output function, there are two registers (Address A66 and A67) at bit D13 for channel A and B respectively, however , the to be disabled pins all are (F1, F2), no (N9, P9) is metioned. Does this description mean (F1, F2) and (N9, P9) are internally directly connnected together, so we only total one 100 ohm resitor for both (F1, F2) and (N9, P9)?
Thank you very much.
