Description

Bonding mode

Non-bonded or x1
Bonded or xN
fb_compensation

Select Non-bonded or x1 to use separate clock

sources for each channel. (This option is available for

Cyclone V and Arria V devices.) If one PLL drives

multiple channels, PLL merging is required. During

compilation, the Quartus II Fitter, merges all the

PLLs that meet PLL merging requirements. Refer to

Merging TX PLLs In Multiple Transceiver PHY

Instances

on page 16-57 to observe PLL merging

rules.
Select Bonded or xN to use the same clock source for

up to 6 channels in a single transceiver bank,

resulting in reduced clock skew. You must use

contiguous channels when you select ×N bonding. In

addition, you must place logical channel 0 in either

physical channel 1 or 4. Physical channels 1 and 4 are

indirect drivers of the ×N clock network.
Select fb_compensation (feedback compensation) to

use the same clock source for multiple channels

across different transceiver banks to reduce clock

skew. (This option is only available for Stratix V

devices.)
