NEW
High-Speed Differential Signal Connectors
EXT Series
1 Gbps Eye Pattern Waveform
(One End of Connector: 2 m of AWG #28 Twinax Cable)
The construction supports high-speed differential signals
such as LVDS, IEEE 1394, and USB 2.0. Use of twisted pair
cable or twinax cable permits transmission speeds up to
several hundred Mbps and higher per twisted pair.
(A) Impedance Matching
The connector is designed to minimize reflections with a
differential impedance of 100 ohms between adjacent contacts.
(B) Low Skew Construction
An equivalent electrical length is maintained between
adjacent contacts while the equivalent electrical length
between opposing terminals is approximately zero.
Consequently the skew within differential pairs as well as
between differential pairs is approximately zero.
However, a low skew between differential pairs is permitted
by going through another layer of the board.
(C) Low Crosstalk
The design features a staggered arrangement between
opposing contacts for low crosstalk effects between opposing
pairs even though these are low-profile connectors.

02. Batch Wiring of Cables Using Solder Paste
Soldered wiring has been used as the wiring method for the
plug side composite cable, thin cable, and drain wires;
however, paste soldering permits the batch wiring of
prepared cables. (Existing soldering methods can also be
used to wire the connectors.)
03. No Shrink Tubing Required
The wiring portion of the plug side is secured by the
molding which prevents short circuits without the use of
shrink tubing. Since shrink tubing is not used, this
allows the twist back length of the twisted pair cable or
the twinax cable to be shortened, thereby permitting the
impedance of the wiring section to be kept in check.
04. Power and Signal Contacts
The 65 position connector is designed with 59 signal contacts and 6 power contacts. Each power contact is
rated for 2 Amps. The 71 position connector is supplied with signal contacts only.
05. Low-Profile Design
With the trend toward lower profiles, the receptacle is made to drop into the board, which results in a height
dimension, including the board, of 5.6mm.

■Technical Notes 2
●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.

●Anchoring to the Case
Mounting of the receptacle connectors makes use of screws to fasten the connectors to the case as illustrated in the
diagram below. This contributes to a structure that is resistant to twisting.

●A Design that Doesn't Use Heat-Shrink Tubing
The soldered wiring portion of the plug connector is secured to the molding which serves as a measure against the
short-circuiting of adjacent contacts. This eliminates the need to attach heat-shrink tubing.
The plug connector has been furnished with a retaining plate made of resin material for the purpose of preventing
short circuits with the metal portions of the cover case.

●Batch Wiring of Plug Connectors
These connectors permit the batch soldered wiring of cables prepared with paste solder and partial reflow.
(Regularly soldered wiring is used for power supply contacts.)

high-speed transmission characteristics.
