12G_PREEMPH_WIDTH

12:8

R/W

Configure the 12G rate pre-emphasis

pulse width on trace driver output1

(DDO1).



Range: 0 to 15d.

Adjust the pre-emphasis pulse width to

better match the channel loss response

shape.



Note: When per rate settings are

chosen, the trace driver 12G settings are

applied for all rates when the Reclocker

is unlocked



(see CTRL_OUTPUT1_TRDR_PER_RATE

for per rate setting).

6R/W

Power down the 12G rate pre-emphasis

on trace driver output1 (DDO1)



0 = Pre-emphasis driver powered up

(pre-emphasis enabled).



1 = Pre-emphasis driver powered down

(pre-emphasis disabled).

Note: When per rate settings are

chosen, the trace driver 12G settings are

applied for all rates when the Reclocker

is unlocked



(see CTRL_OUTPUT1_TRDR_PER_RATE

12G_PREEMPH_AMPL

5:0

R/W

Configure the 12G rate pre-emphasis

amplitude on trace driver output1

(DDO1).



Range: 0 to 50d.

Adjust the pre-emphasis pulse

amplitude to better match the channel

loss at Nyquist.



Note: When per rate settings are

chosen, the trace driver 12G settings are

applied for all rates when the Reclocker

is unlocked



(see CTRL_OUTPUT1_TRDR_PER_RATE

for per rate setting).
