Hi,

Closed window time is mentioned typical value(=twd/4) only. on the datasheet

However the twd is guaranteed min/max value.

Actually, is closed window time guaranteed(min:18/4=4.5ms max;22/4=5.4ms)?

I have moved this post to help ensure the proper experts can address it, though I believe they are out for the holidays.

Hi Kuramochi-san,

the closed window time, tWD_FAIL is a ratio as you mention twd/4. twd is specific with minimum and maximums so yes, the closed window time minimum is 18 ms / 4 = 4.5 ms and the maximum is 22 ms / 4 = 5.5ms (when spread spectrum is not used).

Hi Karamachi-san,

Sorry for the delay due to the holidays. Yes, twd and twd_fail are a specified parameter in the datasheet, so they are guaranteed parameters.

Because of the holidays, TI E2E™ design support forum responses will be delayed from Dec. 25 through Jan. 2. Thank you for your patience.
