DS90UB928Q-Q1: txout0+ to GND resistance

Dongbao Zhou

Part Number: DS90UB928Q-Q1

hello,

Could you help confirm the resistance range of TXOUT0+ pin to GND?

We found a failure unit of ds90ub928q-q1 with comparable lower resistance (8kohm) than good unit (22kohm), which cause abnormal display.

Thanks

Dongbao

    Hi Dongbao, 

    I am looking into locating the material that will provide the resistance range. Thank you for your patience, I hope to get back to you in 1-2 business days. 

    The 8K and 22K is quite comparable, what are the resistances measured for the other TXOUT pins for that failing device?

    Best,

    Shu

    Hi Dongbao, 

    Can you share more about how the 928 is failing? What kind of abnormal display are they seeing? Has the signal integrity in the system been checked and ruled down the 928 TXOUT? I was not able to find the resistance range of that pin as it is not something we spec. 

    Best,

    Shu
