• Low power, 23mA active mode

• Bi-directional redriving, low latency, auto qualified

• Compensate signal loss over 5 meter cable while

passing compliance

• Robust interoperability for CarPlay and Android

Auto

• CarPlay compliance with up to 5 meter cable

• Battery charging and data transferring

simultaneously anywhere in the car
