General Description
The VSC7132 is a high performance serial Link Replicator for applications in Fibre Channel (1.0625Gb/s),
Gigabit Ethernet (1.25Gb/s) and HDTV (1.485Gb/s). 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 SerDes (VSC7123) or Serial
Backplane IC (VSC7211) where the VSC7132 provides redundant, hot-swappable links to redundant Switch
Fabric Cards. Another common application is in Host Adapters which require an internal and an external connector where the VSC7132 steers serial data between the SerDes (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 SerDes on OUT.

OUTPUT - Differential: High-speed Serial Outputs.
INPUT - TTL: OE0/OE1 enables OUT0/OUT1 when HIGH. When LOW, OUTx is
powered down and both OUTx+ and OUTx- float HIGH.
High-speed Output Power Supply: 3.3V supply for PECL drivers. VDDP0 is for
OUT0, VDDP is for OUT, and VDDP1 is for OUT1.
