1
The minimum/maximum specifications are guaranteed over the 40°C to +85°C temperature range (TMIN to TMAX).
2
Guaranteed by characterization.
3
Refers to all I2C pins (DDC and control port).
4
The prefix x refers to pin names beginning with S, DDCA_S, and DDCB_S.
5
SDP timing figures were obtained using the default drive strength value (0x15) in User Map Register 0xF4.
6
CP timing figures were obtained using the maximum drive strength value (0x3F) in User Map Register 0xF4.
7
The suffix x refers to pin names ending with 0, 1, 2, and 3.
