Unused. These pins should be connected to DGND.
30
CLKIN_A
I
Pixel Clock Input for HD Only (74.25 MHz), ED
1
Only (27 MHz or 54 MHz) or SD Only (27 MHz).
63 CLKIN_B
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.
50
S_HSYNC
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.
49
S_VSYNC
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.
22
P_HSYNC
I
ED/HD Horizontal Synchronization Signal. See the External Horizontal and Vertical
Synchronization Control section.
23
P_VSYNC
I
ED/HD Vertical Synchronization Signal. See the External Horizontal and Vertical Synchronization
Control section.
24
P_BLANK
I
ED/HD Blanking Signal. See the External Horizontal and Vertical Synchronization Control section.
48 SFL/MISO
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.
47 R
SET1
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
SET1
to
AGND. For low drive operation (for example, into a 300 Ω load), a 4.12 kΩ resistor must be
connected from R
SET1
to AGND.
