The SN75LVCP600 is
a versatile single channel, SATA Express signal conditioner supporting data rates up to
6 Gbps. The device supports SATA Gen
1, 2, and 3 specifications as well as PCIe 1.0, 2.0, and 3.0. The SN75LVCP600 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.
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 3 Gbps and lower the SN75LVCP600 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.
Two de-emphasis levels can be selected on the transmit side to provide 0 dB or 1.2 dB of
additional high-frequency loss compensation at the output.
The device is hot-plug capable(1) preventing device damage
under device hot-insertion such as async signal plug and
removal, unpowered plug and removal, powered plug and removal, or surprise plug and removal.
