VOD_CTRL_SETTING
Integer No Specifies, in mV, the value of the V
OD
control signal.
Values are
400, 800, 1000, 1200, 1400, 1600. If
omitted, the default is
1000.
USE_PREEMPHASIS_
CTRL_SIGNAL

used. If you enable this parameter, the
tx_preemphasisctrl port is used and the
PREEMPHASIS_CTRL_SETTING parameter is
ignored. Values are
ON and OFF. If omitted, the default
is
OFF.
PREEMPHASIS_CTRL_
SETTING
Integer No Specifies, as a percentage of the V
OD
control setting,
the value of the pre-emphasis control signal. Values
are
0, 1, 2, 3, 4, or 5. If omitted, the default is 0.
USE_RX_CLKOUT
String No Specifies whether the output clock from the transceiver
block receiver channel is used. Values are
ON and
OFF. If omitted, the default is OFF. If you enable this
parameter, the
rx_clkout port must be used.
USE_RX_CRUCLK
String No Specifies whether the clock recovery unit (CRU) is

input clock. Values are
ON and OFF. If omitted, the
default is OFF. If you enable this parameter, the
rx_cruclk port must be used.
RX_PPM_SETTING
Integer No Specifies the value of the PPM threshold between the
transceiver block receiver PLL VCO and the clock
recovery unit (CRU). Values are
125, 250, 500, or
1000. If omitted, the default is 1000.

String No
Specifies whether the
tx_coreclk[] port is used.
Values are
ON and OFF. If omitted, the default is OFF.
FLIP_RX_OUT
String No Specifies whether the transceiver block receiver
channel output data bits are flipped. Values are
ON and
OFF. If omitted, the default is OFF.
FLIP_TX_IN
String No Specifies whether the transceiver block transmitter
channel input data bits are flipped. Values are
ON and
OFF. If omitted, the default is OFF.
INSTANTIATE_
TRANSMITTER_PLL
