6.3.7 I2S Timer Interface Characteristics
1. Guaranteed by characterization, not tested in production.
2. The maximum value of 256 x Fs is 50 MHz (APB1 maximum frequency).
Note: Refer to the I2S section of RM0383 reference manual for more details on the sampling
frequency (Fs). f

value of these parameters might be slightly impacted by the source clock accuracy. D
CK
depends mainly on the value of ODD bit. The digital contribution leads to a minimum value
of (I2SDIV / (2 x I2SDIV + ODD) and a maximum value of (I2SDIV + ODD) / (2 x I2SDIV +
ODD). F
S
maximum value is supported for each mode/condition.
