Accuracy of CLK signal for ADV7511

How frequency accurate must the pixel clock (CLK) signal be for an ADV7511?  I need 74.25MHz for a 1080p30 output driven by a Virtex-6, and I'm thinking of using one of the Virtex-6's MMCMs to make the clock.  The Coregen output gets close (74.262 MHz per the report):is this small difference critical to the display locking to the signal?  All syncs and data will of course be clocked by this signal so they will all be in sync.
