PARAMETER
Typical values are at +25°C, nominal supply voltages, unless otherwise indicated.
Voltages referenced to ground.
Limits at -40°C are guaranteed by design and not production tested.

Guaranteed by design and not production tested.
Frequency stability vs. temperature is defined as (Δf
Maximum power-supply variations to meet the specification are 5%.
Crystal vendor specification.
Holdover is defined as (f
to bridge the undefined region of the falling edge of SCL.
This is automatically the case if the device does not stretch the low period of the SCL signal. If such a device does not
stretch the low period of the SCL signal, it must output the next data bit to the SDA line t
1250ns before the SCL line is released.
