You may observe increased jitter on an active transmitter channel with CMU PLL while resetting adjacent transceiver channels. This problem is caused when the CMU PLL high speed serial clock is enabled or disabled simultaneously on the adjacent channels, which causes a sudden local increase in the current consumption and jitter on the active transmitter channel.
