Link Replicator for Fibre
Channel, Gigabit Ethernet,
HDTV and SATA
Up to 1.5 Gb/s
The NB4N1158 is a high performance 3.3 V Serial Link Replicator
which provides the function of serial loop replication and serial
loopback control commonly required in Fibre Channel, GbE, HDTV
and SATA applications. Other popular applications include Host Bus

hot-pluggable links between redundant switch fabric cards.
IN is sent to both OUT0 and OUT1; each output is enabled by OE0
and OE1 when HIGH. OUT0 can select either IN or IN1 via the
MUX0 pin. Likewise, OUT1 can select between IN or IN0 via the
MUX1 pin. 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 Adapter 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.
The NB4N1158 is packaged in a 4.7 mm x 9.7 mm TSSOP-28.
