TI SN75LVCP601 Two-Channel SATA 6Gb/s Redriver
Texas Instruments SN75LVCP601 Two-Channel SATA 6Gb/s Redriver and Signal Conditioner supports data rates up to 6Gbps. This TI device complies with SATA physical link 2m and 3i specifications. SN75LVCP601 dual-channel SATA redriver operates from a single 3.3V supply and has 100Ω line termination with a self-biasing feature, making the device suitable for AC coupling. The inputs incorporate an out-of-band (OOB) detector that automatically squelches the output while maintaining a stable common-mode voltage compliant to the SATA link. SN75LVCP601 is also designed to handle spread-spectrum clocking (SSC) transmission per the SATA specification. SN75LVCP601 handles interconnect losses at both its input and output. The input stage of each channel offers selectable equalization settings that can be programmed to match the loss in the channel. The differential outputs provide selectable de-emphasis to compensate for the distortion that the SATA signal is expected to experience. The level of equalization and de-emphasis settings depends on the length of interconnect and its characteristics.
