3 Description

The SN75LVCP601 device is a dual-channel, singlelane

SATA redriver and signal conditioner supporting

data rates up to 6 Gbps. The device complies with

SATA physical link 2m and 3i specifications. The

SN75LVCP601 operates from one 3.3-V supply and

has 100-Ω line termination with a self-biasing feature,

making the device suitable for ac coupling. The inputs

incorporate an out-of-band (OOB) detector, which

automatically squelches the output while maintaining

a stable common-mode voltage compliant to the

SATA link. The device design also handles spreadspectrum

clocking (SSC) transmission per the SATA

specification.

The SN75LVCP601 device handles interconnect

losses at both its input and output. The input stage of

each channel offers selectable equalization settings

that are programmable to match the loss in the

channel. The differential outputs provide selectable

de-emphasis to compensate for the expected

distortion that the SATA signal experiences. The level

of equalization and de-emphasis settings depends on

the length of interconnect and its characteristics. The

setting of signal control pins EQ1, EQ2, DE1, and

DE2 controls both equalization and de-emphasis

levels.

This device is hot-plug capable (requires the use of

ac-coupling capacitors at differential inputs and

outputs), thus preventing device damage under

device hot-insertion, in such cases as: async signal

plug or removal, unpowered plug or removal,

powered plug or removal, surprise plug or removal
