Description
SDRAM Clocks. SDRAM uses these clocks
to sample all control, address, and data lines.
To ensure that the Suspend mode functions
correctly, SDCLK3 and SDCLK1 should be
used with CS1#. SDCLK2 and SDCLK0
should be used together with CS0#.
SDRAM Clock Input. The SC3200 samples
the memory read data on this clock. Works in
conjunction with the SDCLK_OUT signal.
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.
