In the figure shown below, we are using the 2nd configuration of the elastic store buffer. This configuration fully
utilizes the elastic store buffer and allows the user a delay accommodation of 0 to 14 ns. The PULSE delay must
follow the PCLK delay. It is very important that the relationship between these two signals be kept all the way
through the loop. Otherwise it is possible to under or over spill the buffer. It is important to insure that the PULSE
signal is retimed along with the outgoing data to the S3043.
