Anchor1. Background of I-PEX developed products for the enterprise market

In recent years, infrastructure telecommunications equipment, such as servers and switches, have become increasingly fast in the enterprise market.
A key challenge for this equipment is that conventional PCB trace transmission has large insertion losses with limited transmission distance. 
A co-package system also faces the challenge of high-density packaging. I-PEX has begun development of our new LEAPWIRE®/DUALINE® series 112 Gbps PAM4 using high-speed twinax cables, MEZZTRACK™ series 112 Gbps PAM4 board-to-board connection and 64 Gbps PAM4 with paddle card harness solutions to solve these problems. These products will be used for transmission between chips inside equipment and connection to I/O connectors.

Anchor2. DUALINE® & LEAPWIRE®

DUALINE®

DUALINE® series is the name of I-PEX's twinax cable connectors designed for high-speed transmission.

dualine-195-110

LEAPWIRE®

LEAPWIRE® is the name of the high-speed transmission jumper solution by I-PEX.

Challenge

The problem is that the existing board transmission pattern (shown in Fig. 1) has high insertion loss in the PCB trace transmission. Also, because of the large connector size of the general jumper harness, the connector is placed far from the heat sink, and the I/O connector is connected through the board, resulting in a large transmission loss (shown in Fig. 2). In our proposed design (shown in Fig. 3), the connector height has a low profile, allowing for placement under the heat sink, putting it closer to the ASIC. Direct connection to I/O connectors is now possible, which helps reduce transmission loss. The small size of the connector also supports airflow measures.

Anchor3. Transmission distance comparison of Low-Loss PCB (Dk3.7) vs I-PEX LEAPWIRE® (twinax cable)

I-PEX LEAPWIRE® (twinax cable) can transmit approximately 10.3 times farther in the 28 GHz band than Low-Loss PCB(Dk3.7)transmission.

Anchor4. Co-Packaging Trend

Co-packaging is intended to address the challenges of bandwidth and power consumption. It is an advanced mixed-mounting technology that combines electronic components with an IC on a single substrate package. In the next step, it is envisioned that optics and electronic switching will be combined on a single substrate package. Reducing power consumption and thermal effects while reducing the footprint using this technology has become a challenge for the efficient support of high-speed networks. The system also allows the package itself to be replaced in the event of a failure, providing greater design flexibility. As previously mentioned, faster and more efficient transmission and higher density packaging are challenges. Therefore, smaller connectors and jumper solutions, which are capable of high-speed transmission, are needed.

To solve the above issues, I-PEX developed three products for the enterprise computing market.
