SerDes IC

Clockless Link SerDes IC is a differential interface IC that transmits serialized data in pairs utilizing ROHM’s transmission protocol.
Single-pair transmission enables high-speed, long-range communication.
Single-pair bidirectional transmission is also supported, enabling the use of coaxial and STP cables.
This high-speed communication IC is ideal for automotive infotainment and advanced driver assistance systems (ADAS).
