High performance 3.3V serial link replicator

The NB4N1158 is a high performance 3.3V serial link replicator packaged in 4.7mm x 9.7mm TSSOP-28, providing serial loop replication and serial loopback control capabilities commonly required in Fibre Channel, GbE, HDTV and SATA applications. Other popular applications include host bus adapters for routing between internal and external connectors, and hot swap links between redundant switch fabric cards.

IN is sent to both OUT0 and OUT1; Each output is enabled at HIGH via OE0 and OE1. OUT0 can be selected IN or IN1 via the MUX0 pin. Similarly, OUT1 can choose between IN or IN0 with the MUX1 pin. Out can choose between IN0 and IN1.

In a link replicator application, such as a line card to a switch card link, In is transmitted to OUT0 and OUT1, where IN0 or IN1 is selected in OUT. In a host adapter application, In connects to OUT0(the internal connector), which returns data on IN0. IN0 is looped to OUT1(the external connector), which returns the data on IN1 and then back to SerDes on OUT
