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?
