8 Timing Requirements: Across Output Serialization Modes

Table 1 and Table 2 provide details for the 4x serialization timing requirements for DRVDD = 3.3 V and DRVDD = 1.8 V, respectively. Table 3 and Table 4 provide details for the 3x serialization timing requirements for DRVDD = 3.3 V and DRVDD = 1.8 V, respectively. Table 5 provides the details for the 2x and 1x serialization timing requirements for DRVDD = 1.8 V to 3.3 V.
