RX PMA iteface FIFO mode

Registe

Elastic

Selects the RX PMA Iteface FIFO mode. Default value is Elastic. Refe to PMA Diect Mode Suppot fo moe ifomatio,
Eable x_pmaif_fifo_empty pot O/Off Eables the pot that idicates the RX PMA Iteface FIFO's empty coditio. Default value is Off.
Eable x_pmaif_fifo_pempty pot O/Off Eables the pot that idicates the RX PMA Iteface FIFO's patially empty coditio. Default value is Off.
Eable x_pmaif_fifo_pfull pot O/Off Eables the pot that idicates the RX PMA Iteface FIFO's patially full coditio. Default value is Off.
RX Coe Iteface Paametes
RX coe iteface FIFO mode

Phase compesatio

Elastic 0

Specifies the mode fo the RX Coe Iteface FIFO. Default value is Phase compesatio.
Eable RX double width tasfe O/Off Eables double width RX data tasfe mode. I this mode, coe logic ca be clocked with a half ate clock. Default value is O.
Eable x_fifo_full pot O/Off Eables the optioal o_x_fifo_full status output pot. This sigal idicates whe the RX coe FIFO has eached the full theshold. This sigal is sychoous with o_x_clkout. Default value is Off.
Eable x_fifo_empty pot O/Off Eables the optioal o_x_fifo_empty status output pot. This sigal idicates whe the RX coe FIFO has eached the empty theshold. This sigal is sychoous with o_x_clkout. Default value is Off.
Eable x_fifo_pfull pot O/Off Eables the optioal o_x_fifo_pfull status output pot. This sigal idicates whe the RX coe FIFO has eached the specified patially full theshold. Default value is Off.
Eable x_fifo_pempty pot O/Off Eables the optioal o_x_fifo_pempty status output pot. This sigal idicates whe the RX coe FIFO has eached the specified patially empty theshold. Default value is Off.
Eable x_fifo_d_e pot O/Off Eables the optioal i_x_fifo_d_e cotol iput pot. This pot is used fo Elastic FIFO mode. Assetig this sigal eables the ead fom RX coe FIFO. You must eable this ead eable whe usig Elastic FIFO. Default value is Off.
RX Clock Optios
Selected x_clkout clock souce

Wod Clock

RX Use Clock

Sys PLL Clock

Specifies the o_x_clkout output pot souce. Default value is Sys PLL Clock.
Fequecy of x_clkout Output Displays the fequecy of o_x_clkout i MHz based o o_x_clkout souce selectio.
Eable x_clkout2 pot O/Off Eables the optioal o_x_clkout2 output clock. Default value is Off.
Selected x_clkout2 clock souce

Wod Clock

RX Use Clock

Sys PLL Clock

Specifies the o_x_clkout output pot souce. Default value is Wod Clock.
x_clkout2 clock div by 1, 2, 4 Selects the RX clock out 2 divide settig that divides out the o_x_clkout2 output pot souce. Default value is 1.
Fequecy of x_clkout2 Output Displays the fequecy of o_x_clkout2 i MHz based o o_x_clkout2 souce selectio ad o_x_clkout2 clock divide by facto.
RX Use Clock Settigs
RX use clock div by 12-139.5 Divisio facto fom Fvco of RX CDR to RX use clock. Values fom 12 to 139.5 ae acceptable i 0.5 icemets. Default value is 100.
RX use clock Fequecy Output Displays the fequecy of RX use clock i MHz based o RX use clock divide by facto.
