DESCRIPTION
The SN75LVCP412A is a dual channel, single lane SATA redriver and signal conditioner supporting data rates
up to 3.0 Gbps that complies with SATA specification revision 2.6.
The SN75LVCP412A operates from a single 3.3-V supply. Integrated 100-Ω line termination with self-biasing
make the device suitable for AC coupling. The inputs incorporate an OOB detector which automatically turns the
differential outputs off while maintaining a stable output common-mode voltage compliant to SATA link. The
device is also designed to handle SSC transmission per the SATA specification.
The SN75LVCP412A handles interconnect losses at both its input and output. The built-in transmitter
pre-emphasis feature is capable of applying 0 dB or 2.5 dB of relative amplification at higher frequencies to
counter the expected interconnect loss. On the receive side, the device applies a fixed equalization of 7 dB to
boost input frequencies near 1.5 GHz. Collectively, the input equalization and output pre-emphasis features of
the device work to fully restore SATA signal integrity over extended cable and backplane pathways.
The device is hot-plug capable⁽¹⁾ preventing device damage under hot-insertion such as async signal
plug/removal, unpowered plug/removal, powered plug/removal, or surprise plug/removal.
(1) Requires use of AC coupling capacitors at differential inputs and outputs.
