Figure 4-7 shows the I/O interface signals of SERDES.
Although containing some of the basic external components, Figure 12-214 must not be considered as an exhaustive guide for the PCB designer. TI provides additional documents for those who are willing to design PCBs and/or fine tune the SerDes.
Table 12-278 describes the external signals of SERDES4 module.
