The final line on this image is ‘ N6 test-chip focusing on the new PHY technology is working in showing promising results’. The reason why PAM-3 is being used in this case is to achieve that higher bandwidth without the extra limitations that PAM-4 requires to be enabled. When we compare NRZ to PAM-3 and PAM-4, we can see the rate of data transfer for PAM-3 is in the middle of NRZ and PAM-4. This gets complex, so here is a table: PAM-3 Encoding What the system does is actually combine two PAM-3 transmits into a 3-bit data signal, such as 000 is an -1 followed by a -1. PAM-3 is a technology where the data line can carry either a -1, a 0, or a +1. PAM-4, at the same frequency, thus has 2x the bandwidth of an NRZ connection. The natural progression is a scheme allowing two bits to be transferred, and this is called PAM-4 (Pulse Amplitude Modulation), with the 4 being the demarcation for how many different variants two bits could be seen (either as 00, 01, 10, or 11). This is talking about how the 0 and 1s are transmitted – traditionally we talk about NRZ encoding, which just allows for a 0 or a 1 to be transmitted, or a single bit. ‘ The PHY will be based on novel PAM-3 modulation technology’. The third line is actually where it gets technically interesting. The second line confirms that this is ‘ USB 80G is targeted to support the existing USB-C ecosystem’, which follows along that Intel is aiming to maintain the USB-C connector but double the effective bandwidth. Off the bat this is double the bandwidth of Thunderbolt 4, which runs at 40 Gbps. In this image we can see a poster on the wall showcasing ‘ 80G PHY Technology’, which means that Intel is working on a physical layer (PHY) for 80 Gbps connections. The photo removed showcases some new information about next-generation Thunderbolt technology. The post contained four photos, but was rapidly deleted and replaced by a photo with three (in the tweet above). An early post on Sunday morning, showcasing Bryant’s trip to the gym to overcome jetlag, was followed by another later in the day with Bryant being shown the offices and the research. Great views…incredible opp to see innovation …a validation lab tour and time with the team…can’t wait to see what tomorrow brings! /GKOddA6TNiĮVP and GM of Intel’s Client Computing Group, Gregory Bryant, is this week spending some time at Intel’s Israel R&D facilities in his first overseas Intel trip in of 2021. That is what happened today.ĭay 1 with the Israel team in the books. The downside of posting to social media is when certain images exposing unreleased information are not vetted by PR or legal, and we get a glimpse into the next generation of technology. An executive visiting various research divisions across the globe isn’t necessarily new, but with a focus on social media driving named individuals at each company to keep their followers sitting on the edge of their seats means that we get a lot more insights into how these companies operate.
