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 Figure 13 with the parameters
specified in Table 36 when measured at the output pins of the device and 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.
