The Ultra-Reliable DVI
TM
receiver block of the gm5115/25 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 16 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 "gm5115/25 Layout Guidelines" document number C5115-SLG-01A.

Note that input formats with resolutions or refresh rates higher than that supported by the LCD
panel are supported as recovery modes only. This is called RealRecovery. For example, it may
be necessary to shrink the image. This may introduce image artifacts. However, the image is
clear enough to allow the user to change the display properties.
Through register programming, the receiver unit may be placed in one of three states:
Active:
The receiver block is fully on and running.
Standby:
Only the RC (clock) channel remains active. Data and other control signals are not
decoded.
Off:
The receiver block is powered down.
