Table 12-29: 10GBASE-R BER Checker Parameters

Parameter

Range

Description

Enable rx_10g_highber port

(10GBASE-R)

On/Off

When you turn this option On, the TX

10G PCS datapath includes the

rx_10g_

highber

output port. This signal is

asserted to indicate a BER of >10

4

. A

count of 16 errors in 125- m s period

indicates a BER > 10

4

. This signal is

only available for the 10GBASE-R

protocol.

Enable rx_10g_highber_clr_cnt port

(10GBASE-R)

On/Off

When you turn this option On, the TX

10G PCS datapath includes the

rx_10g_

highber_clr_cnt

input port. When

asserted, the BER counter resets to 0.

This signal is only available for the

10GBASE-R protocol.

Enable rx_10g_clr_errblk_count port

(10GBASE-R)

On/Off

When you turn this option On, the 10G

PCS includes the

rx_10g_clr_errblk_

count

input port. When asserted, error

block counter that counts the number of

RX errors resets to 0. This signal is only

available for the 10GBASE-R protocol.

64b/66b Encoder and Decoder

The 64b/66b encoder and decoder conform to the 10GBASE-R protocol specification as described in IEEE

802.3-2008 Clause-49. The 64b/66b encoder sub-block receives data from the TX FIFO and encodes the

64-bit data and 8-bit control characters to the 66-bit data block required by the 10GBASE-R protocol. The

transmit state machine in the 64b/66b encoder sub-block checks the validity of the 64-bit data from the

MAC layer and ensures proper block sequencing.
The 64b/66b decoder sub-block converts the received data from the descrambler into 64-bit data and 8-bit

control characters. The receiver state machine sub-block monitors the status signal from the BER

monitor. The following table describes the 64/66 encoder and decoder parameters.

On/Off

When you turn this option On, the 10G PCS records.

This parameter is valid for the Interlaken and

10GBASE-R protocols.

Enable TX 64b/66b encoder

On/Off

When you turn this option On, the 10G PCS

includes the TX 64b/66b encoder.

Enable TX 64b/66b encoder

On/Off

When you turn this option On, the 10G PCS

includes the RX 64b/66b decoder.
