Propagation Delays
Propagation Delays
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 master 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 Figure 12, Data Output Timing Diagram, on page 33, 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.
