ADV7170 and ADV7391 Video Encoder output current tolerance

These two video encoder datasheets specify a max current output of 33ma to 37ma over temperature (-40°C to 85°C).  I am assuming this defines the Min-Max output current tolerance over temperature for these devices.  There is no nominal room temperature tolerance specification.


What would be the room temperature nominal tolerance on the output for these two devices?


The ADV7170 also specifies a voltage reference tolerance.  The ADV7391 does not.  But both devices generate the output current as a function of an Rset resistor value connected to a reference pin.
