Encoder
The character, received from the Input Register or Phase-align
Buffer and Parity Check Logic, is then passed to the Encoder
logic. This block interprets each character and any associated
control bits, and outputs a 10-bit transmission character.
Depending on the configured operating mode, the generated
transmission character may be
The selection of the specific characters generated are
controlled by the TXMODE[1:0], SCSEL, TXCTx[1:0], and
TXDx[7:0] inputs for each character.
Data Encoding
Raw data, as received directly from the Transmit Input
Register, is seldom in a form suitable for transmission across
a serial link. The characters must usually be processed or
transformed to guarantee
When the Encoder is enabled (TXMODE[1] LOW), the
characters to be transmitted are converted from Data or
Special Character codes to 10-bit transmission characters (as
selected by their respective TXCTx[1:0] and SCSEL inputs),
using an integrated 8B/10B Encoder. When directed to encode
the character as a Special Character code, it is encoded using
the Special Character encoding rules listed in Table 29. When
directed to encode the character as a Data character, it is
encoded using the Data Character encoding rules in Table 28.
The 8B/10B Encoder is standards compliant with ANSI/NCITS
ASC X3.230-1994 (Fibre Channel), IEEE 802.3z (Gigabit
Ethernet), the IBM
Video Broadcast (DVB-ASI), and ATM Forum standards for
data transport.
Many of the Special Character codes listed in Table 29 may be
generated by more than one input character. The

command codes can permit operation where running disparity

Following conversion of each input character from eight bits to
a 10-bit transmission character, it is passed to the Transmit
Shifter and is shifted out LSB first, as required by ANSI and
IEEE standards for 8B/10B coded serial data streams.
Transmit Modes
The operating mode of the transmit path is set through the
TXMODE[1:0] inputs. These static three-level select inputs
allow one of nine transmit modes to be selected. The transmit
modes are listed in Table 3
Table 3. Transmit Operating Modes
The encoded modes (TX Modes 3 through 8) support multiple
encoding tables. These encoding tables vary by the specific
combinations of SCSEL, TXCTx[1], and TXCTx[0] that are
used to control the generation of data and control characters.
These multiple encoding forms allow maximum flexibility in
interfacing to legacy applications, while also supporting
numerous extensions in capabilities.
TX Mode 0—Encoder Bypass
When the Encoder is bypassed, the character captured from
the TXDx[7:0] and TXCTx[1:0] inputs is passed directly to the
Transmit Shifter without modification. If parity checking is
enabled (PARCTL LOW) and a parity error is detected, the
10-bit character is replaced with the 1001111000 pattern
(+C0.7 character).
With the Encoder bypassed, the TXCTx[1:0] inputs are
considered part of the data character and do not perform a
control function that would otherwise modify the interpretation
of the TXDx[7:0] bits. The bit usage and mapping of these
control bits when the Encoder is bypassed is shown in Table 4.
In Encoder Bypass mode, the SCSEL input is ignored. All
clocking modes interpret the data the same, with no internal
linking between channels.
TX Modes 1 and 2—Factory Test Modes
These modes enable specific factory test configurations. They
are not considered normal operating modes of the device.
