APPLICATION NOTE:
The PM-WT75 & PM-WT150 versions have been optimized for use with 8B/10B code and NRZ modulation
as used in HOTLinkTM for communication. One of the main advantages of 8B/10B code is the elimination of
baseline wander concerns (DC bias). Methods of encoding that are not DC balanced, such as FDDI 4B/5B
require a compromise in the magnetics design as more turns (higher inductances) are necessary to combat
the DC imbalance. Thus the major design consideration for 8B/10B code was to provide sufficient high end
bandwidth to allow passage of at least the 3rd hamonic. In a system operating at a 266 MHz baud rate this
3rd harmonic is at 399MHz. The PM-WT75 should be used for both 75Ω & 150Ω applications using 8B/10B
coding @ > 266MHz Baud Rates.
