Figure 1. Notch difference Increased thickness DDR4 modules are slightly thicker than DDR3, to accommodate more signal layers. Figure 2. Thickness difference Curved edge DDR4 modules feature a curved edge to help with insertion and alleviate stress on the PCB during memory installation. Figure 3.
HDMI 1.4- HDMI 2.0 Features • HDMI Ethernet Channel - Adds high-speed networking to an HDMI link, allowing users to take full advantage of their IP-enabled devices without a separate Ethernet cable • Audio Return Channel - Allows an HDMI-connected TV with a built-in tuner to send audio data "upstream" to a surround audio system, eliminating the need for a separate audio cable •...
• Increased maximum bus power and increased device current draw to better accommodate power-hungry devices • New power management features • Full-duplex data transfers and support for new transfer types • Backward USB 2.0 compatibility • New connectors and cable The topics below cover some of the most commonly asked questions regarding USB 3.0/USB 3.1 Gen 1.
that with 5-10 times the bandwidth available, USB video solutions should work that much better. Single-link DVI requires almost 2Gbps throughput. Where 480Mbps was limiting, 5Gbps is more than promising. With its promised 4.8Gbps speed, the standard will find its way into some products that previously weren't USB territory, like external RAID storage systems.
USB Power Delivery The USB PD specification is also closely intertwined with USB Type-C. Currently, smartphones, tablets, and other mobile devices often use a USB connection to charge. A USB 2.0 connection provides up to 2.5 watts of power — that'll charge your phone, but that's about it. A laptop might require up to 60 watts, for example.
