TCAN1463-Q1: equivalent parasitic capacitance

Part Number: TCAN1463-Q1


Hi team,

What are the typical and maximum values of the equivalent parasitic capacitance for TCAN1463 CAN_H, CAN_L, CAN_RX, and CAN_TX? The chip datasheet only provides the maximum values for CAN_TX and CAN_H/CAN_L. OEM VW specifically requires the equivalent capacitance of CAN_H/CAN_L to be less than 10pF, but the datasheet shows a maximum of 20pF.

Below are the requirements from VW:

    Hi Daniel, 

    OEMs requirement is less than the mentioned max. Hence, no concerns. 
    Any below 100 pF for CANH / CANL works okay similar to the data sheet’s characterization data (table 7.10). 15 pF is typical for TXD / RXD and no concerns for less, thanks. 

    Best Regards,

    Michael.
