The SN75LVCP601 device is a dual-channel, single-lane SATA redriver and signal
conditioner supporting data rates up to 6 Gbps. The device complies with SATA physical link 2m and
3i specifications. The SN75LVCP601 operates from one 3.3-V supply and has 100-Ω line termination with
a self-biasing feature, making the device suitable for ac coupling. The inputs incorporate an
out-of-band (OOB) detector, which automatically squelches the output while maintaining a stable
common-mode voltage compliant to the SATA link. The device design also
handles spread-spectrum clocking (SSC) transmission per the SATA specification.
The SN75LVCP601 device handles interconnect losses at both its input and output.
The input stage of each channel offers selectable equalization settings that
are programmable to match the loss in the channel. The differential outputs provide selectable de-emphasis
to compensate for the expected distortion that the SATA signal experiences. The level of equalization and
de-emphasis settings depends on the length of interconnect and its characteristics.
The setting of signal control pins EQ1, EQ2, DE1, and DE2 controls both
equalization and de-emphasis levels.
This device is hot-plug capable (requires the use of ac-coupling
capacitors at differential inputs and outputs), thus preventing device damage under device
hot-insertion, in such cases as: async signal plug or removal, unpowered plug or removal, powered
plug or removal, surprise plug or removal
