ADV7123 and ADV7125 sync levels

The ADV7123 and ADV7125 are high-speed video DACs (10 bit and 8 bit respectively).  A recent customer query has highlighted the fact that the diagrams in the datasheets (figures 3 and 5 respectively) imply that the sync portion of the output video signal is 43 IRE.  The customer measured 40 IRE.  Measurements in our lab on a DC setup support the customer findings.  Results are attached.  The datasheet will be updated in due course.
