Table 1 is a truth table detailing the data flow through the VSC7121. Figure 1 shows a timing diagram of the
data relationship in the VSC7121. There are no critical timing (setup, hold, or delay) parameters for the
VSC7121 as this part routes the serial data encoded with the baud clock that is extracted by a Fibre Channel
receiver. The primary AC parameter of importance is the jitter or data eye degradation inserted by the port
bypass circuit. The design of the VSC7121 minimizes jitter accumulation by using fully differential circuits.
This provides for symmetric rise and fall delays as well as noise rejection.
