Description

10G PCS protocol mode

basic

interlaken

sfi5

teng_baser

teng_sdi

Specifies the protocol that you intend to

implement with the Native PHY. The

protocol mode selected guides the

MegaWizard in identifying legal settings

for the 10G PCS datapath. Use the

following guidelines to select a protocol

mode:
basic : Select this mode for when

none of the other options are

appropriate. You should also select

this mode to enable diagnostics, such

as loopback.

interlaken: Select this mode if you

intend to implement Interlaken.

sfi5 : Select this mode if you intend

to implement the SERDES Framer

Interface Level 5 protocol.

teng_baser : select this mode if you

intend to implement the 10GBASE-R

protocol.

teng_sdi : 10G SDI

10G PCS/PMA interface width

32, 40, 64

Specifies the width of the datapath that

connects the FPGA fabric to the PMA.

FPGA fabric/10G PCS interface width

32
40
50
64
66
67

Specifies the FPGA fabric to TX PCS

interface width .
The 66-bit FPGA fabric/PCS interface

width is achieved using 64-bits from the

TX and RX parallel data and the lower

2-bits from the control bus.
The 67-bit FPGA fabric/PCS interface

width is achieved using the 64-bits from

the TX and RX parallel data and the

lower 3-bits from the control bus.

10G TX FIFO

The TX FIFO is the interface between TX data from the FPGA fabric and the PCS. This FIFO is an

asynchronous 73-bit wide, 32-deep memory buffer It also provides full, empty, partially full, and empty

flags based on programmable thresholds. The following table describes the 10G TX FIFO parameters.
