Description
8-Bit Pixel Port. Y0 is the LSB. Refer to Table 36 for input modes.
8-Bit Pixel Port. C0 is the LSB. Refer to Table 36 for input modes.
8-Bit Pixel Port. S0 is the LSB. Refer to Table 36 for input modes.
Unused. These pins should be connected to DGND.
Pixel Clock Input for HD Only (74.25 MHz), ED
Pixel Clock Input for Dual Modes Only. Requires a 27 MHz reference clock for ED operation or a
74.25 MHz reference clock for HD operation.
SD Horizontal Synchronization Signal. This pin can also be configured to output an SD, ED, or HD
horizontal synchronization signal. See the External Horizontal and Vertical Synchronization
Control section.
SD Vertical Synchronization Signal. This pin can also be configured to output an SD, ED, or HD
vertical synchronization signal. See the External Horizontal and Vertical Synchronization Control
section.
ED/HD Horizontal Synchronization Signal. See the External Horizontal and Vertical
Synchronization Control section.
ED/HD Vertical Synchronization Signal. See the External Horizontal and Vertical Synchronization
Control section.
ED/HD Blanking Signal. See the External Horizontal and Vertical Synchronization Control section.
Subcarrier Frequency Lock (SFL) Input. The SFL input is used to drive the color subcarrier DDS
system, timing reset, or subcarrier reset.
This pin is used to control the amplitudes of the DAC 1, DAC 2, and DAC 3 outputs. For full-drive
operation (for example, into a 37.5 Ω load), a 510 Ω resistor must be connected from R
AGND. For low-drive operation (for example, into a 300 Ω load), a 4.12 kΩ resistor must be
connected from R
