DS90UB954-Q1: Question about DS90UB954TRGZRQ1

Part Number: DS90UB954-Q1

Hi expert,

DS90UB954-Q1 is evaluating on customer side. There are several question about this device. Could you help us to understand it? Thanks.

1. Total Power consumption

Total power consumption showed in Datasheet. But the V(VDD18)=1.89V; V(VDDIO)=3.6V; PT= 564mW. If V(VDDIO)=1.8V. Do we have power consumption data?

2.Power consumption on different speed

It described in 6.5 of datasheet. When FPD-Link Line-rate= 4.0Gbps, the max current on VDD18 is 188mA; When FPD-Link-rate= 1.867Gbps, the max current on VDD18 is 205mA. High speed for low power consumption. Could you help us to understand it?

When FPD-Link line-rate= 1Gbps, VDD18=VDDIO= 1.8V, What's the max current on VDD18 and VDDIO?

3.If RIN1+、RIN1-、CLK1P、CLK1N、XOUT is unused, how to deal with it?

Best Regards

    Hi, regarding the issues listed above, pls check:

    1. No, we have no such data, meanwhile,it is not necessarily as you must take care of the worst case to evaluate your power consumption if considering the power variation.

    2. no we have no such data, we just gave some typical cases for character

    3. you can follow up d/s guideline.

    regards,

    Steven
