Customer question:
1) What is the single line impedance & impedance
differential & differential impedance. Impedance more smaller
more better?
2) impedance 80 +/- 10% ,what's mean of "+/- 10%" ,is
tolerance? This range is the bigger the better, or the smaller the
better?
Our answer:
1) The single line is a line impedance ,differential =
differential refers to the impedance of two parallel lines.
Impedance values depend on the performance of electronic
components.
2) +/- 10% means tolerance. The smaller tolerance on
behalf of the higher requirements, making tecnology more harder
