SONET/SDH/ATM OC-48 8:1 TRANSMITTER
January 7, 2000 / Revision G
The S3041 utilizes a unique elastic store buffer which can be set in two different configurations allowing the
system designer to be flexible in the way a system is to be layed out. The configuration of the elastic store buffer
is dependent upon the I/O pins which comprise the Synch Timing loop. This loop is formed from PULSE(I/P) to
READ(O/P) and PCLK(I/P) to PICLK(O/P). The elastic store buffer can be thought of as a memory stack with a
read pointer. The PULSE signal is the read pointer which announces that it has read a register and when fed
back to READ input, it synchronizes the write operation of the buffer so as not to simultaneously write over the
same register that it has read previously.
In the figure shown above, we are using the second configuration of the elastic store buffer. This configuration
fully utilizes the elastic store buffer and allows the user a delay accommodation of 0 to 13ns. 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 S3041.
