Figure 37. ORSO82G5 Transmit FPGA Interface OPC2 Cell Mode
When operating in the eight-link cell mode, the OPC8 block passes user cells from FPGA to embedded core.
Depending upon the congured CELL SIZE, cell transfers will take a variable number of SYSCLK156 cycles to be
transmitted across the interface. Data are always transferred across a 160-bit bus (20 octets per clock cycle).
Figure 38 shows ve clock cycles for a cell transfer this corresponds to a User Cell size of 91 octets. The two con-
trol signals in the gure are dened as:
sdo_bp_8: Backpressure signal from core instructing user to stop sending cell data. User should complete trans-
mitting the current cell and can send one more cell before deasserting cellvalid.
cellvalid: Is high throughout a cell transfer to indicate valid cell data
