Timing constraints:
Table 21: Timing constraints
To be compatible with external power-on/internal power-down modes (ex: external VDD on and
PDN low), all input pads from baseband side as well as SCL and SDA pads on both sensor and
baseband sides are “fail-safe”.
The “timing constraints” mentioned above correspond to the minimum delay needed between
signals, in order to follow a correct power up sequence and insure an adequate initialization phase.
Referring to the application schematics (
POR pin (internal supply) to RST pin (Reset).
