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 52 with the parameters specified in Table 61 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
