Digital Display Working Group (DDWG), the group that created the Digital Visual Interface (DVI) standard, doesn't seem to exist anymore, so here's an archived copy of the DVI specification:

An interesting note is the DVI specification doesn't actually specify a maximum pixel clock, only that pixel clocks greater than 165 MHz must use two links. In fact, it states the first link can operate beyond 165 MHz if the pixel clock is greater than 330 MHz.
