Input/
Output Description
I 8-Bit Pixel Port. Y0 is the LSB. Refer to Table 31 for input modes.
I 8-Bit Pixel Port. C0 is the LSB. Refer to Table 31 for input modes.
I 8-Bit Pixel Port. S0 is the LSB. Refer to Table 31 for input modes.
I Unused. These pins should be connected to DGND.
I Pixel Clock Input for HD Only (74.25 MHz), ED
I 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.
I/O 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.
I/O 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.
I ED/HD Horizontal Synchronization Signal. See the External Horizontal and Vertical
Synchronization Control section.
I ED/HD Vertical Synchronization Signal. See the External Horizontal and Vertical Synchronization
Control section.
I ED/HD Blanking Signal. See the External Horizontal and Vertical Synchronization Control section.
I/O Multifunctional Pin: Subcarrier Frequency Lock (SFL) Input/SPI Data Output. The SFL input is
used to drive the color subcarrier DDS system, timing reset, or subcarrier reset.
I 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
