Parameter
Type
Description
enable_dpa_fifo
String
Indicates whether the DPA FIFO buffer is
enabled for this channel.You must enable the
rx_dpa_locked
port and
enable_dpa_mode
parameter if this parameter is specified. The
values are
ON
and
OFF
. If omitted, the default
value is
ON
. This parameter is available for
Stratix GX devices in DPA mode only.
enable_dpa_initial_phase_
selection
String
Specifies whether the
dpa_initial_phase_
value
parameter is enabled. The values are
ON
and
OFF
. If omitted, the default value is
OFF
.
When set to
OFF
, the
dpa_initial_phase_
value
parameter value is set to
0
.
enable_dpa_mode
String
Turns on DPA mode. The values are
ON
and
OFF
. If omitted, the default value is
OFF
.
enable_dpa_pll_calibration
String
The values are
ON
and
OFF
. The default value is
OFF
. Set this parameter to
ON
or
OFF
if you are
instantiating the ALTLVDS_RX IP core in DPA
mode with PLL calibration.
enable_soft_cdr_mode
String
Specifies whether the
rx_divfwdclk
port is
used. When set to
ON
, the
rx_divfwdclk
port is
driven by the DPA clock, and then it is divided
down by the deserialization factor. When set to
ON
, the DPA FIFO is bypassed and
rx_fifo_
reset
and
reset_fifo_on_first_lock
are
ignored. The values are
ON
and
OFF
. If omitted,
the default is
OFF
.
implement_in_les
String
Specifies whether to implement SERDES
circuitry in logic cells, which allows the circuitry
to behave similar to Stratix LVDS circuitry. Use
the
implement_in_les
parameter for SERDES
functions that require data rates that are lower
than the dedicated circuitry. Values are
ON
and
OFF
. Note that the receiver IP core starts
capturing the LVDS stream at the first rising
edge of the fast clock, after the PLL has locked.
This is intended for slow speeds and the bit
alignment may be different from a hard
SERDES implementation.
