PCIe 4.0: A Quick Primer on New Features

‘Big Data’, ‘IoT’, ‘Mobile’, ‘Networking’ and ‘Storage’ applications are the key drivers for next generation high-performance systems. To meet the bandwidth requirement of the emerging applications, it was required to either increase the lane width or speed. Increasing the lane width isn’t cost effective and thus increasing speed is the best viable option. PCIe 4.0 has doubled the per lane throughput to 16GT/s, compared to 8GT/s for PCIe 3.0, delivering higher performance without increasing the lane width.

SAS 24G: Beyond the 2x Speed

SAS (Serial Attached SCSI) continues to be the interface of choice for mission-critical storage sub-systems. SAS 24G is more than just a 2x speed-bump over previous generation of SAS 12GB, rather it’s a major overhaul of the technology.

LPDDR4: What Makes It Faster and Reduces Power Consumption

DRAM memories are the ‘heart’ of any computational device, e.g. smart phones, laptops, servers etc. LPDDR4 was mainly designed to increase memory speed and efficiency for mobile computing devices such as smartphones, tablets, and ultra-thin notebooks.  It supports speeds up to 4267Mbps (double the speed of LPDDR3) and 1.1 V input/output buffer power, along with many other improvements compared to its predecessor (LPDDR3/LPDDR2). Below is a comparison of key features between all the three generations of LPDDR.

Ever Wonder How USB Type-C Works?

In our previous Type-C blog – What’s New with USB TYPE-C, we looked at why Type-C is the next-generation adaptor, which is thinner with multipurpose capabilities, making it quite handy to the end consumer. Along with fulfilling the power/charging abilities, it intends to proxy several cable plugs like VGA, HDMI, beefy USB Type-A connector, etc. Predominant responsibility of Type-C connector is supplying/sourcing current and data transmission and reception. Ever wonder how does this dynamic connector work?

Connecting DisplayPort to Multiple Devices

In our previous blog – Unraveling the Topologies of DisplayPort 1.4/1.3, we discussed SST (Single Stream Transport) topology in DisplayPort to transmit single stream from source to sink devices. We also touched upon basics of MST (Multi Stream Transport) topology to transmit multiple streams to single/multiple devices. In this blog we will delve into the different ways in which MST can be leveraged and how MST is used in real scenarios. We will also discuss DisplayPort over USB Type-C, the future of the Display industry.
