DESCRIPTION
The SN75LVCP422 is a dual channel, single lane SATA redriver and signal conditioner supporting data rates up
to 3 Gbps. The device complies with SATA specification revision 2.6 and eSATA requirements.
The SN75LVCP422 operates from a 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 maintaining a stable output common-mode voltage compliant to SATA link. The
device is also designed to handle SSC transmission per SATA spec.
The SN75LVCP422 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 device 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.
