3 Description
The SN75LVPE801 is a versatile single channel,
SATA Express signal conditioner supporting data
rates up to 8 Gbps. The device supports SATA Gen
1, 2, and 3 specifications as well as PCIe 1.0, 2.0,
and 3.0. The SN75LVPE801 operates from a single
3.3-V supply and has 100-Ω line termination with self-
biasing feature, making the device suitable for AC
coupling. The inputs incorporate an out-of-band
(OOB) detector, which automatically squelches the
output when the input differential voltage falls below
threshold while maintaining a stable common-mode
voltage. The device is also designed to handle
spread spectrum clocking (SSC) transmission per
SATA standard.
The SN75LVPE801 handles interconnect losses at its
input with selectable equalization settings that can be
programmed to match the loss in the channel. For
data rates of 8 Gbps and lower the SN75LVPE801
equalizes signals for a span of up to 50 inches of
FR4 board material. For data rates of 8 Gbps the
device compensates up to 40 in of FR4 material. The
equalization level is controlled by the setting of the
signal control pin EQ.
