When parity checking and the encoder are both enabled
(TXMODE[1]  LOW), the detection of a parity error causes a
C0.7 character of proper disparity to be passed to the transmit
shifter. When the encoder is bypassed (TXMODE[1] = LOW),
detection of a parity error causes a positive disparity version of
a C0.7 transmission character to be passed to the transmit
shifter.

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 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, TXCT[1:0], and TXD[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 the TXCT[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
character as a data character, it is encoded using the data
character encoding rules in
The 8B/10B encoder is standards compliant with ANSI/NCITS
ASC X3.230-1994 (fibre channel), IEEE 802.3z (gigabit
ethernet), the IBM
broadcast (DVB-ASI) standards for data transport.
Many of the special character codes listed in
generated
CYP(V)(W)15G0101DXB
independent (but non-overlapping) special character code
tables. This allows the CYP(V)(W)15G0101DXB to operate in
mixed environments with other Cypress HOTLink devices using
the enhanced Cypress command code set, and the reduced
command sets of other non-Cypress devices. Even when used
in an environment that normally uses non-Cypress special
character codes, the selective use of Cypress command codes
can permit operation where running disparity and error handling
must be managed.
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 3-level select inputs allow one of
nine transmit modes to be selected. The transmit modes are
listed in
The encoded modes (TX modes 3 through 8) support multiple
encoding tables. These encoding tables vary by the specific
combinations of SCSEL, TXCT[1], and TXCT[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
a minimum transition density (to allow the serial receive PLL to
extract a clock from the data stream)
a DC-balance in the signaling (to prevent baseline wander)
run-length limits in the serial data (to limit the bandwidth of the
link)
the remote receiver a way of determining the correct character
boundaries (framing).
