Terms of Art

4. Ethernet Ports Are Out, USB Type-C Ports Are In
Slim industrial designs are making bulky Ethernet ports obsolete
The RJ451 port is 9.85-mm high
The Macbook Air scrapped the Ethernet port in 2012; Ultrabooks and Chromebooks are following suit
The new 2.56-mm USB Type-C port will make today’s 5.1-mm USB 3.0 Type-A port even smaller
Customers still want Gigabit Ethernet connectivity
Increasing network traffic (e.g., 4K video, HD iTunes movies) is driving the continued need for Gigabit Ethernet
Neither 100-Mbps Fast Ethernet nor 300-Mbps Wi-Fi provides enough bandwidth for Gigabit Ethernet
USB 3.0 is emerging as the interface of choice for Gigabit Ethernet connectivity
USB 3.0 delivers 5.0 Gbps bandwidth, which is sufficient for Gigabit Ethernet applications
All new PCs have USB 3.0 ports; soon they will have USB Type-C ports
USB Type-C enables sleek designs with Gigabit Ethernet connectivity

6. Design Problems Engineers Face
1. A custom driver is required for every operating system (OS)
There is no standard USB Ethernet device class available
2. Conventional USB 3.0 to GigE bridge controllers lack the throughput of PCIe-based GigE controllers
Converting GigE data packets to USB 3.0 data packets reduces the throughput of conventional USB 3.0 to GigE bridge controllers
to around Mbps
3. Managing the Power Policies of both USB 3.0 and GigE standards is difficult
A USB 3.0 to GigE solution must support both USB 3.0 low-power modes and IEEE 802.3az Energy Efficient Ethernet
Cypress’s GX3 solves these problems by providing
Comprehensive driver support for all major OSs, including Windows 8.x/7/XP, Mac OS, Linux, Android and Chrome
Throughput of 910-Mbps, comparable to the 950-Mbps throughput of PCIe-based GigE solutions
A low-power solution that complies with both USB 3.0 and GigE power policies
GX3 is a low-power, high-throughput USB 3.0 solution that easily adds GigE connectivity to any system
