    how to calculate the number of address lines ?

    how many address lines ? I got one doubt regarding bus interface . A peripheral of 512 Mbits has 16 bit data bus width. I need to calculate the total number of address lines of the peripheral. If it is 512 Mbyte and 16 bit databus width then ,as per my understanding the total number of...

    overshoot and undershoot

    I have one doubt.Can the overshoot value exceed the absolute maximum rating specified for it in the datasheet?

    Do we have to meet skew limit ?

    Re: skew What I feel is set up and hold time parameters have a dependency on skew value also.Skew changes will affect the set up and hold time.Youe have said there is no violation of hold and set up time requirements which implies that skew value is not causing any problem. But the marginality...

    Questions about overshoot at the pin

    Re: Overshoot Thanks for the suggestion.:D But this is found in the product which is under use.So we cant go for any external changes.In this case how can we predict the reliability of the device used on the board? 1.Will the device work with this scenario?If so how long will it work ?How to...

    Questions about overshoot at the pin

    I need to know whether the following scenario will affect the my device :| One input pin of the device receives a clock signal.The absolute maximum allowable overshoot at the pin was given as 5 V.The supply voltage is 4.3V .But while taking the signal quality capture a discrepancy is...
