G2
Channel A Receiver Data Outputs. Parallel data on this bus is valid
on the rising edge of RCAP in full clock mode and valid on rising
edge of both RCAP and RCAN in half clock mode.

F2
Channel A End of Frame Detected. A High on this output indicates
that a valid K28.5 has been detected and is present on the parallel
data outputs DOUTA[0:7]. (See Table 7.)
KFLAGA
G3
Channel A K-Character Flag. A High in KFLAGA indicates that a
valid control character has been detected. Data present on the
parallel interface DOUTA[0:7] should be used to indicate which
character was received. (See Table 7.)
ERRA
LOLA
TTL
TTL
O
O
G1
C5
Channel A Receive Error. A High on ERRA signifies the
occurrence of either a parity error or an invalid codeword error
during decoding of the received data. (See Table 7.)
Channel A Loss of Lock Detected. LOLA High indicates that the
CRU on channel A has lost bit lock. This signal will deassert when
the CRU has locked to data. When in Channel Lock Mode, this
signal will assert indicating that the channel A CRU is not bit
locked. This will report asynchronously. (See Table 7.)
RCAP

K2
K1
Receive Data Clock for Channel A. Parallel receive data,
DOUTA[0:7], EOFA, KFLAGA, and ERRA are valid on the rising
edge of RCAP when in full clock mode and valid on the rising edge
of both RCAP and RCAN in half clock mode.

Channel B Receiver Data Outputs. Parallel data on this bus is valid
on the rising edge of RCBP in full clock mode and valid on rising
edge of both RCBP and RCBN in half clock mode.

L1
Channel B End of Frame Detected. A High on this output indicates
that a valid K28.5 has been detected and is present on the parallel
data outputs DOUTB[0:7]. (See Table 7.)
KFLAGB
P2
Channel B K-Character Flag. A High in KFLAGB indicates that a
valid control character has been detected. Data present on the
parallel interface DOUTB[0:7] should be used to indicate which
character was received. (See Table 7.)
