The primary purpose of the USB 2.0 signal conditioner is to restore the signal integrity of a USB High-Speed channel to USB 2.0 compliant levels. The platform goal is to pass the USB Near-End or Far-End Eye Mask with the device in the best location.
A typical use case is to place the USB 2.0 signal conditioner close to the USB connector on a Host platform to pass Near-End Eye Mask testing. This includes systems where the USB connector may be placed at the Far-End of a cable.
Typical RX Sensitivity and Boost recommendations based on cable length (28 AWG USB Cable) are shown in Table 3-4. We recommend starting with the lower settings first.
| Cable Length | Boost | RX SEN |
|---|---|---|
| 0m - 2m | Level 0 | MID |
| 3m-5m | Level 1 | MID / HIGH |
