Propagation Delays for PIXCLK and
Data Out Signals
The typical output delay, relative to the master
clock edge, is 7.5 ns. Note that the data outputs change
on the falling edge of the master clock, with the pixel
clock rising on the subsequent rising edge of the mas-
ter clock.
Propagation Delays for FRAME_VALID
and LINE_VALID Signals
The LINE_VALID and FRAME_VALID signals
change on the same falling master clock edge as the
data output. The LINE_VALID goes HIGH on the same
falling master clock edge as the output of the first valid
pixel's data and returns LOW on the same master clock
falling edge as the end of the output of the last valid
pixel's data.
As shown in the “Output Data Timing” on page 9,
FRAME_VALID goes HIGH 6 pixel clocks prior to the
time that the first LINE_VALID goes HIGH. It returns
LOW at a time corresponding to 6 pixel clocks after the
last LINE_VALID goes LOW.
