Part Number: DS90UH929-Q1

Hi team,

Could you please kindly help to confirm which parameter should i refer to for the working voltage and working current range of the pin Dout+/Dout- on the datasheet, following are the parameter customer want to know and the parameter we can found on datasheet, could you please kindly help to confirm if the parameter shows on the attached picture is the parameter that customer are asking? But i still not sure with which parameter should I refer for the working type voltage and min&max output current, could you please also kindly help to give some explanation about these value? Thank you very much for your kindly support.

Function Definition	Working voltage			Working Current
Function Definition	Min	type	Max	Min	type	Max

Pls refer to d/s page9 on the item. "FPD-LINK III DIFFERENTIAL DRIVER", it has the spec. request which is based on CML output structure.

Hi steven,

Thank you very much for your kindly reply.

May i confirm with you again about the working current on Dout+/Dout- pin, since the parameter shows on page 9 is the Ios(output short circuit current), and i can't found any description about the working current, could you please kindly help to give more explanation about it? Thank you again for your kindly help,

Best regards

Jessica

Jesscia,

for the working current, pls calculate it as:

AC current I = Vp (~500mV) / termination resistor (50ohms) =~10mA.

best regards,

Steven
