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.

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. 2001.6 1 ■Product Specification Ratings Operation temperature range –55ç to +85ç Voltage 125 V AC Current Item 1.

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. GND DATA2 GND DATA2 ;;; DATA1 DATA1 ;; ●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.

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.
