DP159 Power sequencing Requirements

PSB

Hi,

I have a customer who is designing with the DP159 (DisplayPort) re-timer and would like to know if there are any power sequencing requiremnts for this device. Datasheet does not give this information. Please advise.

Thanks,

Hi Pritpal,

Please request an updated product preview internally. The documentation now includes power sequencing information. Vcc must be stable at the same time or up to 200 us before Vdd.

Hello,

Where can I find info about DP159 ?

I can only find DP130 as a retimer for 5.4Gbps/lane

Jorge

Hi Jorge,

As this device has not been released yet we can't open share datasheet.
Please send me an email to JoseCarlos.Gil@TI.com and I will share datasheet.

Regards.

Hi JMMN,

I seen on the datasheet that VDD (1V1) must be stable before VCC (3V3) with max 200us, this will complicate a little bit the schematic, because I must delay the main power (3V3).

I'm right?
