SONET Mode Block Alignment – ORSO82G5
Figure 28 describes the clocks and recommended clocking for block alignment in the SONET mode. For block
alignment, the low speed portion for each block should be sourced by a single clock. As the gure shows, for block
A, RSYSCLKA1 and RSYSCLKA2 should be sourced by RCK78A. For block B, RSYSCLKB1 and RSYSCLKB2
should be sourced by RCLK78B. RCLK78A can be sourced by any channel in block A and RCLK78B can be
sourced by any channel in block B.

SONET Mode Octal Alignment – ORSO82G5
Figure 29 shows the clocking scheme for eight-channel alignment. In this application, all four clocks RSYSCLKA1,
RSYSCLKA2, RSYSCLKB1 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.
