Serial RapidIO
For each baud rate at which an LP-serial transmitter is specified to operate, the output eye pattern of the
transmitter shall fall entirely within the unshaded portion of the transmitter output compliance mask shown
in
the device is driving a 100-Ω ± 5% differential resistive load. The output eye pattern of an LP-serial
transmitter that implements pre-emphasis (to equalize the link and reduce inter-symbol interference) need
only comply with the transmitter output compliance mask when pre-emphasis is disabled or minimized.
