The Ultra-Reliable DVI receiver block of the gm5060 is compliant with DVI1.0 single link
specifications. Digital Visual Interface (DVI) is a standard that uses Transition Minimized
Differential Signaling protocol (TMDS). This block supports an input clock frequency ranging
from 20 MHz to 165 MHz.

4.4.1 DVI Receiver Characteristics
Table 12 summarizes the characteristics of the four Receiver Pair inputs. Please note that it is
very important to follow the recommended layout guidelines for these signals. These are
described in "gm5020/5060 System Layout Guidelines" document number C5020-APN-01.
