Quad-Port SerDes for ASA Motion Link

AVL5004 family of quad-port serializer/deserializer (SerDes) provides an ASA (Automotive SerDes Alliance) Motion Link compliant solution to securely distribute video and sensor data within Automotive ADAS systems.

A pair of AVL5004 devices supports multi gigabit connections for high-resolution camera, lidar and radar sensors used in safety-critical ADAS (Advanced Driver Assistance Systems) and autonomous driving systems by converting the high-speed video from the MIPI CSI-2 interface and data from control interfaces to an ASA Motion Link interface and vice versa. Each of the four ASA ports on these devices can be configured in firmware either as a transmitter (serializer mode) or a receiver (deserializer mode), enabling several use cases with a single serializer/deserializer device. Each ASA port on the AVL5004 chipsets can support line rates from 2 Gbit/s - 16 Gbit/s (Speed Grades 1/2/3/4/5) over a single low-cost 50 Ω Coax or 100 Ω STP cable. The ASA Motion Link Physical Layer is based on time division duplexing (TDD), resulting in lower power consumption, implementation complexity and solution size.

The AVL5004 family of serializer/deserializer devices supports the complete ASA security framework, including standardized interoperable link-based security as well as a 3-level Key Exchange Entity, to ensure device/data authentication and protection across the automotive supply-chain. These serializer/deserializer devices also include a suite of functional safety and diagnostic features that provide end to end link monitoring and reliability for safety-critical ADAS and autonomous driving applications.
