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
