High Speed, Matched-Impedance, Parallel Board-to-board Connector

IT1 Series

Receptacle (2 required)

IT1 Series Outline

High-speed matched-impedance parallel board-to-board

connector designed for applications requiring board-to-

board spacing with transmission speeds exceeding

1GHz. The connection system has matched impedance

of 50 ohm or can be customized. Contacts are on 0.5mm

pitch.

s Features

1. Impedance Matching using a 4-Layer Board

The innovative transmission module uses PC boards

with a strip line design of transmission lines, providing

matched impedance of 50 ohms, for standard product.

2. Supports Multiple Connectors per board

Designed with a tolerance of +/- 0.2mm for both the X

and Y-axis. The three-piece structure and the +/- 0.2mm

tolerance allows 3 or more IT1’s to be mounted on a

single board.

3. Customized Board-to-Board Distance

Board-to-board distance can be customized, from 16mm

to 40mm.

Ground lines or additional traces can be added to

support high level, high speed transmission or mixed

power/signal applications.

4. Signal to Ground Ratio

The standard signal-to-ground ratio is 10:2, which makes

reliable matching of the characteristic impedance of each

transmission line. This ratio also can be customized.

5. Contact Reliability

Use of double contact points on each of the contacts

assures highly reliable performance.
