Cypress Semiconductor has announced a new high-throughput, low-power SuperSpeed USB controller that converts Gigabit Ethernet (GigE) data to USB 3.0 data. The goal of the EZ-USB GX3 controller is a slimmer laptop design that includes an ultra-thin USB Type-C port without a bulky Ethernet port. GX3 provides comprehensive driver support for all major operating systems (including Windows, Mac OS, Linux, Android, and Chrome), thus enabling USB 3.0 ports on any system (including laptops, tablets, docking stations, IP sets) Seamless plug and play operation. Set-top boxes and smart TVs.
Conventional USB 3.0 to GigE bridging solutions present designers with limited throughput performance and power management challenges. For throughput, converting a GigE packet to a USB 3.0 packet reduces the throughput of a traditional USB 3.0 to GigE bridge controller to approximately 700-800 Mbps. EZ-USB GX3 uses a proprietary data transmission mechanism, which can send multiple GigE packets through USB bursts to provide 910-Mbps throughput, which is comparable to the 950-Mbps throughput of the native GigE solution. For power supply, it is difficult for traditional USB 3.0 to GigE solutions to support both USB 3.0 and GigE standard low power modes, but GX3 provides a power saving solution with multiple power saving modes.
Mark Fu, senior marketing director for USB 3.0, said: "Apple MacBooks removed the Ethernet port a few years ago, Ultrabooks and Chromebooks have followed suit, but consumers still want GigE connectivity to transmit high-definition content and for other applications that require high bandwidth Applications. "Product Family, Cypress. "Whether through a standard USB Type-A port or a new USB Type-C port, our new EZ-USB GX3 solution seamlessly brings high-throughput GigE connectivity to any USB 3.0 system. GX3 is further enhanced With our SuperSpeed USB portfolio, combined with our groundbreaking programmable EZ-PDT USB Type-C power solution and EZ-USB HX3 USB 3.0 hub, Cypress can now provide true single cable docking for the following products The solution: laptops, tablets and other portable devices. "The
EZ-USB GX3 controller includes on-chip Gigabit Ethernet MAC and PHY, supports 802.3az energy-efficient Ethernet and other advanced power management features, including wake-on-LAN, idle or light Dynamic energy-saving mode at current carrying capacity and AutoDetach function with the following features: GX3 is "soft disconnected" from the USB host whenever the Ethernet cable is unplugged. The USB PHY and controller are fully compliant with the USB Link Power Management (LPM) policy, supporting U0, U1, U2, and U3 low-power states. In addition, GX3 includes an IPv4 / IPv6 packet checksum offload engine (COE) to reduce CPU load, and provides IPv4 IP / TCP / UDP / ICMP / IGMP and IPv6 TCP / UDP / ICMPv6 checksums and generates them.
The USB Type-C standard has been quickly supported by top PC manufacturers by implementing a slim industrial design, easy-to-use connectors and cables, the ability to transmit multiple protocols, and the ability to transmit 100W power (PD). The previous 7.5W standard. The USB Type-C standard 2.4mm high connector plug is significantly smaller than the current 4.5mm USB Type-A standard connector. The company says it also allows USB and DisplayPort signals to be transmitted on the same connector.
Cypress also announced that its EZ-PD CCG1 and EZ-PD CCG2 USB Powered (PD) controllers have passed the USB Implementer Forum (USB-IF) certification test program for USB Type-C DRP (dual role port) ), DFP (downstream) port-oriented) and UFP (upstream port-oriented) applications. Cypress controllers received approved product test IDs 1096037, 1096039, 1096040, 1096042, 1096044, and 1096047 at the recently concluded USB-IF compliance workshop event in Portland, Oregon. The EZ-PD controller covers a wide range of market areas such as USB Type-C laptops, power adapters, displays, docking stations, cables and cable adapters (dongles).
