Search tips

apple banana
Find rows that contain at least one of the two words.

+apple +juice
Find rows that contain both words.

+apple macintosh
Find rows that contain the word 'apple', but rank rows higher if they also contain 'macintosh'.

+apple -macintosh
Find rows that contain the word 'apple' but not 'macintosh'.

+apple ~macintosh
Find rows that contain the word 'apple', but if the row also contains the word 'macintosh', rate it lower than if row does not. This is "softer" than a search for '+apple -macintosh', for which the presence of 'macintosh' causes the row not to be returned at all.

+apple +(>turnover >strudel)
Find rows that contain the words 'apple' and 'turnover', or 'apple' and 'strudel' (in any order), but rank 'apple turnover' higher than 'apple strudel'.

Find rows that contain words such as 'apple', 'apples', 'applesauce', or 'applet'.

"some words"
Find rows that contain the exact phrase 'some words' (for example, rows that contain 'some words of wisdom' but not "some noise words").

What is a CAN FD SIC Transceiver?

What is a CAN FD SIC Transceiver?


SIC is the abbreviation for Signal Improvement Capability. A SIC transceiver allows to build more complex network topologies at higher communication bit rates. With current high-speed CAN transceivers 2 MBit/s can be achieved with a linear network topology. 5 MBit/s can be reached with a point-to-point communication. With a SIC transceiver 5 MBit/s can be achieved with networks that use stars and long stub lines (Figure 1).

A SIC transceiver reduces the ringing caused by reflections in a network. Therefore, the sampling of bits gets more robust. In the scope measurements below it can be seen how the signal quality is influenced by a SIC transceiver. The measurement was created with the network shown in Figure 1 and Vector’s VN1640A CAN/CAN FD interfaces using a common CAN high speed transceiver (Figure 2) and a CAN SIC transceiver prototype (Figure 3). The network topology was chosen to demonstrate the ringing effects. However, similar topologies can be found in cars.

SIC transceivers are specified in CiA 601-4. The CiA 601-4 document is provided by CAN in Automation (

SIC transceivers will soon be available from several manufacturers. Vector plans to provide a Piggyback based on a SIC Transceiver for its CAN network interfaces.
