What is serializer/deserializer (SerDes)?
The Automotive SerDes Alliance (ASA) is a non-profit industry alliance of automotive technology providers collaborating to standardize asymmetric SerDes technology. The group currently has more than 160 active member companies that work together to industrialize and promote the “ASA Motion Link”. The member companies of ASA include representatives from the complete automotive ecosystem, including car manufacturers, tier-one suppliers, semiconductor vendors, cable and connector manufacturers, test tool vendors, and test houses.
What downstream and upstream speeds are supported by ASA Motion Link?
- Downstream rates: 16 G/12 G/8 G/4 G/2 G
- Upstream rates: 100 M/50 M
Which automotive cables are supported by ASA Motion Link?
- 50 Ω Coax up to 15 meters with Power Delivery
- 100 Ω STP cable up to 10 meters with Power Delivery
What is time division duplexing (TDD) technology?
The ASA Motion Link defines an asymmetric physucal layer based on TDD. The downstream and upstream traffic are seperated in time during the TDD burst, which means the traffic does not overlap on the wire. This results in significant benefits in terms of power, performance and implementation complexity.
What are the key advantages for automotive applications?
- Configurable ports provide system design flexibility and fewer product variants
- Lower power consumption
- More efficient PoC with smaller solution size
