Hello,
At fast I2C mode, my customer would like to know what could be wrong if tICF (I2C input fall time) is less than the minimum spec, 20+Cb(ns).
This spec is originally specified by NXP I2C spec, but does TI know what would get wrong if the tICF is < minimum spec at TPL0102-100?
Best regards,
K.Hirano
Hi Hirano-san,
I had a similar thread a few days ago about the DAC101C081Q: https://e2e.ti.com/support/data-converters-group/data-converters/f/data-converters-forum/1027667/dac101c081q-can-we-ignore-the-tf-fall-time-min-for-dac101c081qisd-nopb
The same will be true for the TPL0102-100
My response was:
"Not meeting the minimum fall time requirement should have no effect on the DAC101C081Q. The minimum rise and fall times for the fast and high speed modes come from the I2C standard (version 6):
Fast and high speed devices include spike suppression on the SDA and SCL inputs. This DAC supports standard mode which has no minimum fall time, so it should be ok if the minimum fall time is not met when using fast mode or high speed mode."
Best,
Katlynne Jones
