TAS2505: I2C Interface Timing for Fast mode

Sadanori Kato

Part Number: TAS2505
Other Parts Discussed in Thread: TAS2557,

Hi,

According to TAS2505 data sheet, the minimum values of tHD;STA and tSU;STA are 0.8us for the fast mode. On the other hand, those values are 0.6us in TAS2557 data sheet.
Then, those values are 0.6us when checking the I2C bus specifications.
Are those values which are mentioned in TAS2505 data sheet typos?

Hi, Kato-san,

There's no typo on these I2C parameters, the TAS2505 and TAS2557 have different I2C fast mode times due to their internal signals distribution. It allows to have a wider timing range in the TAS2557.
