Ohad,
What type of signals are you attempting to level shift? What type of devices are you connecting that you need to translate 3.3V to 2.5V? Do they have open drain drivers or push-pull drivers? Do you need to do bi-directional communication? …
Hi
I need a n-bits(>20) ,high-speed(>70MHz), 1.8V<->2.5V COMS IO levelshifter for to connecting Vertirx-7 platform and daughterboard, who can recommand a TI product to me, and it's better that the product don't need any direction control…
Other Parts Discussed in Thread: ADS4226 , SN74AVC20T245 , ADS4226EVM Hi,
We are trying to talk with ADS4226 through SPI. But when the readout bit is set 1 and we read any internal registers there is no output from SPI. we are reading the output at SDOUT…
Hi, Ashish,
Yes, you are right. the two parts will have the much skew, and it is diffcult to implent the synchronization between clcok and Data.
But unfortunately, so far, we don't have the bus translator which can work up to 250MHZ. sorry for that.…
Hi KW,
Thanks for the response. We see the same sawtooth wave if we connect to SN74AVC20T245. Also we see the same sawtooth wave if i connect ADS4226 to FPGA input directly.
we are using IBIS model taken from TI site.
thanks

[ SN74AVCxxT245 ] Output Skew Tsk(o)
Hi,
Do you have any numbers of output skew of SN74AVC 20 T245, SN74AVC 24 T245 and SN74AVC 32 T245? This is not specified in the datasheet. It's really helpful, if you have some indications from characterization/verification…
