frame pulse, is less than the minimum threshold set by RX_FIFO_MIN. In the memory map section OOS is referred
to as SYNC2_[A2,B2]_OOS, SYNC4_OOS. OVFL is referred to as SYNC2_[A2,B2]_OVFL, SYNC4_OVFL.
Receive Clocking for Multi-channel Alignment – ORSO42G5
There are a total of seven clocks for the receive path, from FPGA to the core. The two used in SONET mode are
RSYSCLKA2 (for block A), and RSYSCLKB2 (for block B). The following diagrams show the recommended clock
distribution approaches for SONET mode multi-channel alignment modes. Cell mode alignment is discussed in the
section describing the Input Port Controller (IPC).)
SONET Mode Twin Alignment – ORSO42G5
Figure 22 describes the clocking scheme for twin alignment. In twin alignment, the valid channel pairs are AC,AD in
block A and BC,BD in block B. The gure provides the clocking scheme for block A as an example. RSYSCLKA2
should be sourced from RCK78A, RWCKAC or RWCKAD. For the ORSO42G5, the use of RCK78A is recom-
mended since it uses primary clock routing resources. This clocking approach provides the required 0 ppm clock
frequency matching for each pair and provides exibility in applications where the two pairs are received from asyn-
chronous sources.

SONET Mode Quad Alignment – ORSO42G5
Figure 23 shows the clocking scheme for four-channel alignment. In this application, both clocks RSYSCLKA2 and
RSYSCLKB2 should be sourced from a common clock. Either RCK78A or RCK78B can be used as a common
clock source. The gure shows RCK78A being used as the clock source.
