A serializer/deserializer, such as the VSC7123, would normally be connected to the IN+/- and OUT+/- ports in order to provide duplicate links on the IN0/OUT0 and IN1/OUT1 ports. A popular application is for Line Cards using serial links from a Ser Des (VSC7123) or Serial Backplane IC (VSC7211) where the VSC7132 provides redundant, hot-swappable links to redundant Switch Fabric Cards. Another mon application is in Host Adapters which require an internal and an external connector where the VSC7132 steers serial data between the Ser Des (VSC7123) and the two connectors. IN is sent to both OUT0 and OUT1 whose buffers are enabled when OE0 and OE1 are HIGH. OUT1 can select between IN and IN0. OUT can select between IN0 and IN1. In Link Replicator applications, such as the Line Card to Switch Card links, IN is transmitted to both OUT0 and OUT1, which either IN0 or IN1 is selected at OUT. In Host Adaptor applications, IN goes to OUT0 (an internal connector) which returns data on IN0. IN0 is looped to OUT1 (an external connector) which returns data on IN1 and then back to the Ser Des on OUT.
