Question, i.MX1 SSI signal timing specification

[Aemj]

Dear team,

I would like to ask about i.MX1.

My customer is using SSI2_RX and SSI2_TXCLK of i.MX1 as input from external.

They need to know the specification of the input waveform, especially rise/fall time, for the signals but they could not found the specification in i.MX1 datasheet.

Actually, the signals that flow into those pins have 25ns of rise/fall time on their board.

Could you show me whether the 25nS of rise/fall time is acceptable?

Thanks,

Miyamoto

Hi AVNET JAPAN FAE

rise/fall times are not specified, because they are not important.

Important are setup and hold times, these and other important parameters

are provided in datasheet.

Best regards

igor

Dear Igor,

Thanks for your prompt reply.

Can i understand 25nS of rise/fall time is OK?

My customer wants your comment on the rise/fall time.

Hi Miyamoto

yes this rise/fall time is OK.
