TYPE
DESCRIPTION
Input
Transmit Data Pins, Channel B. When PSYNC is low, parallel data on this bus is clocked
on the rising and falling edges of TCB. When PSYNC is high, data on this bus is clocked
on the rising and falling edges of TCA.
Input
Transmit Data/ K-code Flag, Channel B. When PSYNC is low, data on this pin is clocked
on the rising and falling edges of TCB. When PSYNC is high, data on this pin is clocked
on the rising and falling edges of TCA. When CODE is low, this pin is the 9th bit of an
8b/10b-encoded byte to be transmitted. When CODE is high, this pin acts as the K-
character generator indicator. When high, this pin causes the data on TDB(0-7) to be
encoded into a K-character.
Input
Transmit Data Pin, Channel B. When PSYNC is low, data on this pin is clocked on the
rising and falling edges of TCB. When PSYNC is high, data on this pin is clocked on the
rising and falling edges of TCA. When CODE is low, this pin is the 10th bit of an 8b/10b-
encoded byte. When CODE is high, this pin is undefined.
Output
Receive Data Pins, Channel B. When PSYNC is low, parallel data on this bus is valid on
the rising and falling edges of RCB. When PSYNC is high, data on this bus is valid on
the rising and falling edges of RCA.
Output
Receive Data/ K-code Flag, Channel B. When PSYNC is low, data on this pin is valid on
the rising and falling edges of RCB. When PSYNC is high, data on this pin is valid on the
rising and falling edges of RCA. When CODE is low, this pin is the 9th bit of a received
8b/10b-encoded byte. When CODE is high, this pin acts as the K-character flag. When
high, this indicates the data on RDB(0-7) is a valid K-character.
Output
Receive Data Pin/ Error Detect, Channel B. When PSYNC is low, data on this pin is valid
on the rising and falling edges of RCB. When PSYNC is high, data on this pin is valid on
the rising and falling edges of RCA. When CODE is low, this pin is the 10th bit of an
8b/10b-encoded byte. When CODE is high, this pin goes high to signify the occurrence
of either a parity error or an invalid code word during the decoding of the received data.
Input
Transmit Data Pins, Channel C. When PSYNC is low, parallel data on this bus is clocked
on the rising and falling edges of TCC. When PSYNC is high, data on this bus is clocked
on the rising and falling edges of TCA.
Input
Transmit Data/ K-code Flag, Channel C. When PSYNC is low, data on this pin is clocked
on the rising and falling edges of TCC. When PSYNC is high, data on this bus is clocked
on the rising and falling edges of TCA. When CODE is low, this pin is the 9th bit of an
8b/10b-encoded byte to be transmitted. When CODE is high, this pin acts as the K-
character generator indicator. When high, this pin causes the data on TDC(0-7) to be
encoded into a K-character.
Input
Transmit Data Pin, Channel C. When PSYNC is low, data on this pin is clocked on the
rising and falling edges of TCC. When CODE is low, this pin is the 10th bit of an 8b/10b-
encoded byte. When CODE is high, this pin is undefined.
Output
Receive Data Pins, Channel C. When PSYNC is low, parallel data on this bus is valid on
the rising and falling edges of RCC. When PSYNC is high, data on this bus is valid on
the rising and falling edges of RCA.
Output
Receive Data/ K-code Flag, Channel C. When PSYNC is low, data on this pin is valid on
the rising and falling edges of RCC. When PSYNC is high, data on this pin is valid on
the rising and falling edges of RCA. When CODE is low, this pin is the 9th bit of a
received 8b/10b-encoded byte. When CODE is high, this pin acts as the K-character
flag. When high, this indicates the data on RDC(0-7) is a valid K-character.
Output
Receive Data Pin/ Error Detect, Channel C. When PSYNC is low, data on this pin is
clocked on the rising and falling edges of TCC. When CODE is low, this pin is the 10th
bit of an 8b/10b-encoded byte. When CODE is high, this pin goes high to signify the
occurrence of either a parity error or an invalid code word during the decoding of the
received data.
Input
Transmit Data Pins, Channel D. When PSYNC is low, parallel data on this bus is clocked
on the rising and falling edges of TCD. When PSYNC is high, data on this bus is clocked
on the rising and falling edges of TCA.
