RUN_LENGTH
Integer No Specifies the maximum run length supported for the
incoming data signal. This parameter is ignored if the
RUN_LENGTH_ENABLE parameter is turned off. If the
deserialization factor is
8, legal values are 4128, in
multiples of four. If the deserialization factor is 10, legal
values are
5160, in multiples of five. If omitted, the
default is
0.
RUN_LENGTH_ENABLE
String No Specifies whether to use run length detection. Values
are
ON and OFF. If omitted, the default is OFF.
USE_CHANNEL_ALIGN
String No Specifies whether to use the channel aligner and
enable the deskew system. The
USE_CHANNEL_ALIGN parameter can only be used
when the
PROTOCOL parameter is set to XAUI. Values
are
ON and OFF. If omitted, the default is OFF.
USE_AUTO_BIT_SLIP
String No Specifies whether to use internal bit slipping circuitry. If
you enable this parameter, the bitslip transceiver block
receiver channel is ignored, and an internal register
controls the byte alignment functions. If this parameter
is turned off, the bit slipping operation is controlled by
the
rx_bitslip[] signal. Values are ON and OFF.
If omitted, the default is
OFF.
USE_SYMBOL_ALIGN
String No Specifies whether to use the word aligner. Values are
ON and OFF. If omitted, the default is ON.
ALIGN_PATTERN
String No Specifies the pattern of 7, 10, or 16 bits used by the
word aligner for the
USE_SYMBOL_ALIGN parameter.
If the
USE_SYMBOL_ALIGN parameter is turned off,
this parameter is ignored. If the
PROTOCOL parameter
is set to
XAUI or GigE, the only legal pattern is
0101111100.
ALIGN_PATTERN_LENGTH
Integer No
Specifies the length of the
ALIGN_PATTERN
parameter. Values are
7, 10, or 16. If omitted, the
default is
0.
CLK_OUT_MODE_
REFERENCE
String No Specifies whether to use the clock that operates the
post rate matching FIFO module of the transceiver
block receiver channel. This parameter is ignored if the
USE_RATE_MATCH_FIFO parameter is turned off.
Values are
ON and OFF. If omitted, the default is OFF.
USE_SELF_TEST_MODE
String No Indicates whether to use the built-in self test mode.
Values are
ON and OFF. If omitted, the default is OFF.
