Description
SDRAM Clock Output. This output is routed
back to SDCLK_IN. The board designer
should vary the length of the board trace to
control skew between SDCLK_IN and
SDCLK.
Description
Video Port Data. The data is input from the
CCIR-656 video decoder.
Video Port Clock Input. The clock input
from the video decoder.
Description
DDC Serial Clock. This is the serial clock for
the VESA Display Data Channel interface. It
is used for monitor communications. The
DDC2B standard is supported by this inter-
face.
DDC Serial Data. This is the bidirectional
serial data signal for the VESA Display Data
Channel interface. It is used for monitor com-
munications. The DDC2B standard is sup-
ported by this interface.
Horizontal Sync
Vertical Sync
Voltage Reference. Reference voltage for
CRT PLL and DAC. This signal reflects the
internal voltage reference. If internal voltage
reference is used (recommended), leave this
ball disconnected. If an external voltage ref-
erence is used, this input is tied to a 1.235V
reference.
