SONET Mode Operation – Detailed Description
The following sections describe the data processing performed in the SONET logic blocks. The basic data ows in
the SONET Mode are shown in Figure 11. At a top level, the descriptions are separated into processing in the
transmit path (FPGA to serial link) and processing in the receive path (serial link to FPGA). In general, the descrip-
tions in the next sections are written to describe SONET mode operation, although some of the “SONET logic
blocks” are also used in cell mode operation. The various processing options are selected by setting bits in control
registers and status information is written to status registers. Both types of registers can be written and/or read
from the System Bus. Memory maps and descriptions for the registers are given in Table 21 through Table 36.
Figure 11. Basic Data Flows - SONET Mode
In the SONET mode, the transmit block receives 32-bit wide data from the FPGA (DINxx) on each of its channels
along with a frame pulse (DINxx_FP) per channel and a transmit clock (TSYCLKxx). Typically this will represent a
STS-48 stream on each link. The data are rst passed through a TOH block which will generate all the timing
pulses that are required to isolate individual overhead bytes (e.g., A1, A2, B1, D1-D3, etc.). The timing pulse gener-
