Note 1:
In ATM receive applications, SRTSDATA corresponds to the 4-bit difference
calculated between the locally-generated RTS code and the remotely-generated RTS code
received from the incoming ATM cell stream.
Note 2:
The external circuit within the FPGA provides access to the SRTSDATA values in a
parallel format (i.e. stored in a register).
Note 3:
The CPU then accesses the SRTS values stored within the FPGA. A software
algorithm is used to determine if the local clock is too fast or too slow relative to the remote
clock. Based on this algorithm, the DIVX and DIVX Ratio Registers are modified (as in
Adaptive Clock Recovery). Using the new settings in these registers, the MT90500 generates
an 8 kHz output reference clock from REF8KCLK. This signal is routed from the MT90500 to
the external PLL.
