What is the tolerance and temperature coefficient of the internal clock of the PCAN-USB FD?
My bus has 200ppm oscillators at all nodes. It would be great if the PCAN-USB was as accurate.

Hi,
please provide the serial number (IPEH-XXXXXX yyyyyy) of the used PCAN-USB FD device, to see which hardware revision you are using.
regards
Michael

Hello,
clock is based on a crystal with a frequency tolerance of 30ppm and a frequency stability of 30ppm within temperature of -40°C to +85°C. Thererfor the input clock can vary by 60ppm. The CAN output clock is created by using several digital dividers that do not change the accuracy.
