Connection Pattern of Differential Signals
Differential signals should be arranged between adjacent contacts as illustrated in the diagram below for the
purpose of impedance matching and equivalent electrical length. Furthermore, the establishment of a ground will be
effective in reducing the crosstalk between adjacent differential pairs.
Note also that for faster high-speed differential signals, gathering them to the center portion will permit control of the
electrical length at the time of harnessing.

Low Skew Between Opposing Differential Pairs
The electrical length between adjacent contacts is equal, but the electrical length between opposing contacts differs
by approximately 1.2 mm.
As illustrated in the diagram to the right, the differential pair of contacts having a short electrical length on the upper
side of the board can be given an electrical length equivalent to that between the opposing differential pair by
adjusting the electrical length using such methods as through holes in the board.
The crosstalk on the board between differential pairs is also reduced.

Power Supply Contacts Configuration Diagram
The 65-contact type is configured with 6 power supply contacts.
The power supply contacts are divided into 2 leads within the receptacle-side connector (EX60T-C65P) which
results in differing numbers of coupling surface-side contacts and board-side lead portion contacts.
