Receive Serial Data. The differential receive serial data
links (RP[11:0]/RN[11:0]) carry the receive SBI336S or
SONET/SDH STS-12 frame data from upstream sources
in bit serial format. Each differential pair RP[X]/RN[X]
carries a constituent SBI336 or STS-12 stream. Data on
RP[X]/RN[X] is encoded in an 8B/10B format extended
from IEEE Std. 802.3. The 8B/10B character bit ‘a’ is
transmitted first and the bit ‘j’ is transmitted last. All
RP[X]/RN[X] differential pairs must be frequency locked
and phase aligned (within a certain tolerance) to each
other. RP[11:0]/RN[11:0] are nominally 777.6 Mbit/s data
streams.
