ModeThe SN75LVCP422isa dual channel, single lane SATA redriver and signal conditioner supporting data ratesup3 Gbps. The device complies with SATA specification revision 2.6 and eSATA requirements.
The SN75LVCP422 operates froma single 3.3-V supply. Integrated 100-Ω line termination and self-biasing make
the device suitable for AC coupling. The inputs incorporate an OOB detector, which automatically turns the
differential outputs off while maintaininga stable output common-mode voltage compliantto SATA link. The
deviceis also designedto handle SSC transmission per SATA spec.
The SN75LVCP422 handles interconnect losses at both its input and output. The built-in transmitter
pre-emphasis featureis capableof applying0 dBor 2.5 dBof relative amplificationat higher frequenciesto
counter the expected interconnect loss. On the receive side the device appliesa fixed equalizationof7 dBto
boost input frequencies near 1.5 GHz. Collectively, the input equalization and output pre-emphasis featuresof
the device workto fully restore SATA signal integrity over extended cable and backplane pathways.
The deviceis hot-plug capable(1) preventing device damage under device hot-insertion such as async signal
plug/removal, unpowered plug/removal, powered plug/removal,or surprise plug/removal.
(1) Requires useof AC coupling capacitorsat differential inputs and outputs.
