Hello,
Could you please let me know the latency of DS90CF388?
I would like to know the delay time from input the data to output the data.
The input clock is 74.25MHz.

Hi Asaka-san,
We do not have any characterization data available for the latency of the DS90CF388A. However, I was able to reference a similar device that uses an identical package that is comparable as a reference point. For this reference, I looked at the DS90CR484.
The DS90CR484 states that the propagation delay is dependent on the TCIP parameter, which is simply the TxCLKIN period:
Thus, I expect the min/typ/max latency for the DS90CF388A at 74.25 MHz to be around:
Min = 3 / 0.07425 + 4.0 = 44.4 ns
Typ = 3 / 0.07425 + 4.8 = 45.2 ns
Max = 3 / 0.07425 + 6.5 = 46.9 ns
Thanks,
Michael
Hello Michael san,
Thank you for the information.
I would like to confirm the following.
Is the propagation delay correlated with Package size?
And, is the DS90CR484 design same with the DS90CF388A?
