ORCA ORSO42G5 and ORSO82G5 Data Sheet

The behavior of the IPC is dependent on the AUTO_BUNDLE register bit. If AUTO_BUNDLE is set, the group will
continue to operate even if a link (or several links) of the group is not valid (RX_LINK_GOOD is low). If
AUTO_BUNDLE is not set the entire group must be valid (RX_LINK_GOOD is high) for the group to receive cells
through the IPC.
The IPC must determine when FIFO reads may begin. Before reading data from a FIFO can begin, the FIFO must
have a full cell available to be read. This is condition is indicated by a signal from each FIFO which is monitored by
the IPC. The IPC then makes sure that the cells in a given port are received in the order that they are transmitted.
IPC Receive Cell Mode Timing Core/FPGA
This section contains timing diagrams for major interfaces of this block to the FPGA logic when cells are to be
transferred. Figure 45 shows the cell twin-link mode timing. The number of clock cycles to transfer the cell data
depends on the payload size selected. Error indications for CELL BIP errors and CELL DROP are also shown.
Figure 45. IPC2 Data Flow
When operating in CELL MODE, the IPC2 Block passes user cells as well as control and status signals to the user.
Depending upon the congured CELL SIZE, cell transfers will take a variable number of SYSCLK156 cycles to be
received across the interface. Data are always transferred across a 40-bit bus (5 octets per clock cycle). Figure 45
shows 16 clock cycles for a cell transfer. This corresponds to a User Cell size of 79 octets.
Figure 46 shows cell octal alignment mode timing for the ORSO82G5. When operating in CELL MODE, the IPC8
Block aligns all 8 channels of receive data on a FRAME basis. The IPC8 also passes user cells as well as control
and status signals to the user. Depending upon the congured CELL SIZE, cell transfers will take a variable num-
ber of SYSCLK156 cycles to be received across the interface. Data are always transferred across an 160-bit bus
(20 octets per clock cycle). Figure 46 shows 4 clock cycles for a cell transfer. This corresponds to a User Cell size
of 79 octets.

CELL BIP ERROR
If a Cell BIP Error occurs,
the CELL_BIP_ERR signal reects the occurrence, as shown in the
Figure.
For 2-Link CELL MODE,
the CELL_BIP_ERR signal is asserted during the last 4 clock cycles
of the receive cell.

Cell Drop is associated with
the NEXT cell (NOT present)
CELL BIP ERROR
If a cell error occurs within the ASB and;
1. CELL_BIP_INH=0 ...Do not drop BIP errored cells
(s/w selectable)
2. A BIP error occurs
The drop indicator will PRECEED the user cell that con-
tains the BIP error. All data will be passed w/o modica-
tion.
