Figue 42. GTS PMA/FEC Diect PHY Itel FPGA IP Paamete Edito
Table 22.  Commo Datapath Optios Paametes
Paamete Values Desciptio
PMA cofiguatio ules Basic,

DISPLAY PORT ,

OTN,

SDI,

CPRI,

HDMI

Selects the potocol cofiguatio ules fo the GTS PMA. This paamete goves the ules fo coect settigs of idividual paametes withi the PMA.

Cetai featues of the PMA ae available oly fo specific potocol cofiguatio ules. This paamete is ot a peset. You must still coectly set all othe paametes fo you specific potocol ad applicatio eeds.

Default value is Basic.

Numbe of PMA laes Fo TX Simplex ad Duplex : 1, 2, 4, 6, 8

Fo RX Simplex : 1, 2, 3, 4, 6, 8

Specifies the total umbe of PMA laes i a boded goup. Fo example, if the value is 4, this meas thee ae 4 PMA laes boded i the same goup ad shae the same bodig clock. A value of 1 meas thee is o bodig. The umbe of PMA laes is 1 whe FEC is eabled.

Default value is 1.

Datapath clockig mode

PMA

System PLL

Specifies whethe the PMA paallel clock o System PLL is used to clock the TX/RX datapath.

Requied to use System PLL whe Eable FEC is o. Default value is System PLL.

System PLL fequecy 32.5 to 1000 MHz
Specifies the system PLL clock fequecy (MHz) ad applicable if datapath clockig mode is selected as system PLL. Default value is 322.265625 MHz.
Note: You must esue that the system PLL fequecy ad GTS System PLL Clocks Itel FPGA IP fequecy is set to the same value if you ae usig the system PLL clockig mode.
PMA mode Duplex, TX Simplex ad RX Simplex

Specifies the PMA opeatio mode. TX simplex ad RX simplex ca opeate at idepedet ates at diffeet PMA laes. Default value is Duplex.

PMA data ate

E-Seies (Device Goup B):

10312.5 Mbps (default)

17160 Mbps (maximum)

D-Seies ad E-Seies (Device Goup A): 28100 Mbps (maximum)

Specifies the PMA data ate i uits of Mbps (Mb/sec). Default value is 10312.5 Mbps.

PMA paallel clock fequecy Data ate/PMA width Displays PMA paallel clock fequecy which is PMA data ate divided by PMA iteface width i MHz. Default value is Data ate / PMA Width.
PMA width 8, 10, 16, 20, 32

Specifies the PMA data width. Suppoted Data width is 8, 10, 16, 20 ad 32 bit. Default value is 32

Povide sepaate iteface fo each PMA O/Off
Whe eabled, the GTS PMA/FEC Diect PHY Itel FPGA IP pesets sepaate data ad clock itefaces fo each PMA lae, athe tha a wide bus. Default value is Off.
Note: Whe the Eable FEC optio is o, a sepaate iteface is ot available fo each PMA by use of the Povide sepaate iteface fo each PMA optio.
Eable efclock to coe O/Off Eables the efeece clock to FPGA coe featue.

Loopback mode

disabled

paallel

Selects the PMA loopback mode. Default value is disabled.
Note:

Fo the paallel loopback mode, whe you do ot have RX iput seial data comig ito the eceive, you eed to oveide the soft eset cotolle (SRC) by settig the soft CSR egiste 0x10018[0]. I ode fo the TX to RX paallel loopback mode to fuctio, you eed to set this bit to 1'b1 to oveide the SRC fom moitoig the PMA block status. Oce you ae out of TX to RX paallel loopback mode, you ca set this bit back to 1'b0.

You do ot have to cotol this bit if you have RX seial data comig ito the eceive. Refe to the GTS PMA/FEC Diect PHY IP Registe Map fo moe ifomatio.
