3. DETAILED DESCRIPTION
3.1 DATA INPUT AND OUTPUTS
Data enters and exits the device synchronous to the rising
edge of PCLK_IN as shown in Figure 1.
3.2 INPUT BLANKER
Data words entering the GS1511 can be dynamically set to
Luma and Chroma blanking levels if desired as shown in
Figure 3. Blanking is applied to both the LUMA and
CHROMA channels simultaneously.
