Up Coding (in VIP)
The coding technique used on the Up interface is a half-bauded AMI code (with a 50 %
pulse width (refer to
are coded as alternate positive and negative pulses. Code violation (CV) is caused by
two successive pulses with the same polarity.
The AMI coding includes always the data bits going on the Up interface in one direction.
Consequently there is a separate AMI coding unit for data from the DELIC to the VIP
implemented in the VIP, and vice versa.
