Other Parts Discussed in Thread: WL1837, TXB0108
We are using WL1837 MOD in our design for WiFi interface which is interfaced to a host SDIO bus with 3V3 IO logic level. We are using TXS0108EPWR for the translation between 3V3 logic level and 1V8 logic level. But we are observing signal integrity issues on the SDIO signals. The waveform are distorted and there are overshoots and undershoots.
As an alternate we have tried the translator TXB0108 in place of TXS0108. But the SDIO interface is not functional at all when TXB0108 is being used. Is there any known fix for this issue?
