Receiver Eye Diagrams

For each baud rate at which an LP-Serial receiver is specified to operate, the receiver shall meet the

corresponding Bit Error Rate specification (Table 71,Table 72, and Table 73) when the eye pattern of the

receiver test signal (exclusive of sinusoidal jitter) falls entirely within the unshaded portion of the Receiver

Input Compliance Mask shown in Figure 60 with the parameters specified in Table 74. The eye pattern of

the receiver test signal is measured at the input pins of the receiving device with the device replaced with

a 100-

Ω +/– 5% differential resistive load.

Measurement and Test Requirements

Because the LP-Serial electrical specification are guided by the XAUI electrical interface specified in

Clause 47 of IEEE 802.3ae-2002, the measurement and test requirements defined here are similarly guided
