SY897132L
1.5Gbps Link Replicator for Fibre Channel,
Gigabit Ethernet, HDTV and SATA
General Description
The SY897132L is a Link Replicator which provides
both serial loop replication as well as serial loopback
control functions. It is high performance and works up
to 1.5Gbps on 3.3V power supplies. The SY897132L is
ideal for Fibre Channel, Gigabit Ethernet, HDTV and
SATA applications. Other applications include
internal/external connection routing in Host Bus
Adaptors as well as hot-pluggable links between switch
cards.
The IN input is sent to both OUT0 and OUT1, which are
enabled when OE0 and OE1 are HIGH and disabled
when they are LOW. When the outputs are disabled,
both differential outputs go HIGH and the buffers are
turned off to save power.
MUX0 controls whether IN or IN1 is sent to OUT0.
Similarly, MUX1 controls whether IN or IN0 is sent to
OUT1. MUX selects whether IN0 or IN1 is sent to OUT.
The SY897132L operates on 3.3V ±5% power supplies
and is guaranteed over the full industrial temperature
range (–40°C to +85°C). The SY897132L is part of
Micrel’s high-speed, Precision Edge^® product line.
