7.2.1.3 Application Curves

The TDP2004 is a linear redriver that can be used to extend channel reach of a DP link. The redriver can help to pass compliance by removing ISI deterministic jitter at data rates up to 20Gbps (UHBR20). Figure 7-3 - Figure 7-6 shows a typical DP 2.1 Tx compliance channel setup along with compliance Eye Diagrams at TP3_EQ with or without redriver. The comparison of eye diagrams show that TDP2004 can provide signal conditioning by extending horizontal and vertical eye openings that makes a failing eye to pass.
