Texas Instruments  SN75LVPE802RTJR

The SN75LVPE802 is a versatile dual channel, SATA Expresssignal conditioner supporting data rates up to 8 Gbps. The device supports SATA Gen 1, 2, and 3specifications as well as PCIe 1, 2, 3. The SN75LVPE802 operates from a single 3.3-V supply and has100-Ω line termination with self-biasing feature, making the device suitable for AC coupling. Theinputs incorporate an out-of-band (OOB) detector, which automatically squelches the output when theinput differential voltage falls below threshold while maintaining a stable common-mode voltage.The device is also designed to handle spread spectrum clocking (SSC) transmission per SATAstandard.

The SN75LVPE802 handles interconnect losses at its input with selectable equalizationsettings that can be programmed to match the loss in the channel. For data rates of 3 Gbps andlower, the SN75LVPE802 equalizes signals for a span of up to 50 inches of FR4 board material. Fordata rates of 8 Gbps, the device compensates up to 40 in of FR4 material. The equalization level iscontrolled by the setting of the signal control pin EQ.

Two de-emphasis levels can be selected on the transmit side to provide 0 or 1.2 dB ofadditional high- frequency loss compensation at the output.

The device is hot-plug capable (requires use of AC coupling capacitors at differentialinputs and outputs) preventing device damage under device hot-insertion such as async signalplug/removal, unpowered plug/removal, powered plug/removal, or surprise plug/removal.
