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
