Description
Enable Control and
Status Registers
(14)
On, Off
Turn on this option to enable soft registers for reading status
signals and writing control signals on the PHY interface
through the embedded debug. Signals include
rx_is_
locktoref
,
rx_is_locktodata
,
tx_cal_busy
,
rx_cal_busy
,
rx_serial_loopback
,
set_rx_locktodata
,
set_rx_
locktoref
,
tx_analogreset
,
tx_digitalreset
,
rx_
analogreset
, and
rx_digitalrest
. For more information,
refer to the Arria 10 Transceiver User Guide.
Enable Prbs Soft
Accumulators
(14)
On, Off
Turn on this option to set the soft logic to perform PRBS bit
and error accumulation when using the hard PRBS generator
and checker.
JESD204B Configurations Tab
Lanes per converter device
(L)
1–8
Set the number of lanes per converter device.
(15)
Converters per device (M) 1–256
Set the number of converters per converter device.
Enable manual F configu‐
ration
On, Off
Turn on this option to set parameter F in manual mode
and enable this parameter to be configurable. Otherwise,
the parameter F is in derived mode.
You have to enable this parameter and configure the
appropriate F value if the transport layer in your design is
supporting Control Word (CF) and/or High Density
format(HD).
Note: The auto derived F value using formula
F=M*S*N\'/(8*L) may not apply if parameter
CF and/or parameter HD are enabled.
Octets per frame (F)
1, 2, 4–256
The number of octets per frame derived from the formula
of F= M*N'*S/(8*L).
Converter resolution (N) 1–32
Set the number of conversion bits per converter.
Transmitted bits per
sample (N')
1–32
Set the number of transmitted bits per sample (JESD204B
word size).
Note: If parameter CF equals to 0 (no control word),
parameter N' must be larger than or equal to
sum of parameter N and parameter CS (N' ≥ N
+ CS). Otherwise, parameter N' must be larger
than or equal to parameter N (N'≥N).
Samples per converter per
frame (S)
1–32
Set the number of transmitted samples per converter per
frame.
(15)
Refer to the
table for the supported range for L.
