可以通过CAN信号改进来提高FD
NXP半导体正在加大芯片的生产，以提高CAN工业和汽车网络的性能。
TJA146X可以在中国的汽车设计中使用信号提高能力（CAN SIC）收发器来支持更大，更复杂的网络，并通过主动改善CAN信号来提高可实现的数据速率。
Changan Automobile is the first NXP automotive customer to incorporate the CAN SIC technology in production.
新功能推动了达到性能限制的CAN网络系统中增加数据交换的需求，CAN FD是一种比经典能力更高的带宽功能的技术，将比特率从500 kbit/s提高到5 mbit/s，但受信号反射的信号响声遭受。对于许多网络，这有效地将技术限制为2 mbit/s，从而将它们限制在高度线性拓扑中。
这意味着线束需要避免长长的电缆分支，从而导致车辆周围更令人费解的线束路线，从而增加了成本和重量。CAN信号改进收发器克服了通过主动改善CAN信号响起而引起的信号完整性问题，从而在电子控制单元，较短的电缆，更少的重量，更少的连接器和更轻松的网络设计方面具有更大的灵活性。
The technology also extends the performance of CAN FD to enable data rates over Mbit/s on multi-node networks by using active signal enhancements and stricter timing. With these bandwidth improvements, CAN FD is expected to support a higher range of applications at a relatively low cost point.
“自早期阶段以来，Changan和NXP的车载网络团队就在Changan最新的Uni-K模型的ADAS系统中进行了CAN SIC的实施。最大的挑战是解决响应引起的干扰问题。”
“重复模拟，测试和验证证明，CAN SIC技术是解决响声问题的最有效方法。TJA146X可以使我们提高接线线束布局的灵活性，并为将来的升级铺平到更高的速度，例如5Mbps。从整个项目的角度来看，它极大地提高了通信质量和工程效率。”
“With our CAN Signal Improvement technology, carmakers can now create cost-efficient CAN FD networks with the freedom that their vehicle networks demand,” said Meindert van den Beld, VP and General Manager of NXP’s In Vehicle Networking Product Line. “We are delighted that Changan has embraced our TJA146x CAN SIC transceiver series for their new UNI-K model, rapidly adopting this technology into production.”
The TJA146x transceiver series are available as pin-compatible replacements to existing transceivers and comply both with the existing ISO11891-2:2016 CAN FD transceiver specification, as well as the new CiA601-4 Signal Improvement standard for backward compatibility with standard CAN transceivers.
