Refer to Figure 7-9. fSCL I2C DDC clock frequency 100 kHz tBUF Bus free time between START and STOP conditions 4.7 µs tHD_STA Hold time after repeated START condition. After this period, the first clock pulse is generated 4 µs tLOW Low period of the I2C clock 4.7 µs tHIGH High period of the I2C clock 4 µs tSU_STA Setup time for a repeated START condition 4.7 µs tHD_DAT Data hold time 0 μs tSUDAT Data setup time 250 ns tR Rise time of both SDA and SCL signals. Measured from 30% to 70%. 1000 ns tF Fall time of both SDA and SCL signals Measured from 70% to 30%. 300 ns tSU_STO Setup time for STOP condition 4 μs Cb_LV Capacitive load for each bus line on LV side 50 pF Power-On.
