USB Type-C - EEs Talk Tech #1 - Keysight Technologies

USB Type-C is taking over our devices, with guest Jit Lim Click to subscribe! ► http://bit.ly/Scopes_Sub Now available on your favorite podcast platform and at: https://EEsTalkTech.com (an electrical engineering podcast) Visit Keysight's USB Type-C design and test solutions page for app notes and more: http://bit.ly/2elCjCi What does USB Type-C mean for the world? Daniel Bogdanoff (@DanielBogdanoff) and Mike Hoffman sit down with Jit Lim to find out. We discuss super fast charging, blazing data transfer transfer - and, of course, things catching fire as a result. Hosted by Mike Hoffman and Daniel Bogdanoff, EEs Talk Tech is a bi-monthly podcast dedicated to discussing technology and tech news from an engineer's perspective. New episodes available on the 2nd and 4th week of every month. Episode #2 will discuss AI and the decentralization of processors on 8-December.

LED projectors? Noodle makers? 11:45 Q: Can I find a cheap USB Type-C cable? 13:15 A: Probably over time, but if it's poorly implemented it could go badly Phones are blowing up! 14:15 The cable isn't just a wire anymore 14:59 Alt modes: USB is the cable to end all cables! It can handle Displayport, HDMI, VGA, DVI, Thunderbolt, ethernet, power, headphones 15:15 mhl devices No headphone jack!?! 16:00 Is USB Type-C available in stores today? Are manufacturers pushing Type-C or are consumers demanding it? 16:50 USB A to C, USB B to C, Thunderbolt to USB C adapters are allowed in the USB C spec (USB Type-C specification) Look for USB Certification on products 17:40 USB IF mandates that products be certified before being sold (i.e. on Amazon) 18:00 A bad USB Type-C implementation can destroy your stuff! 18:45 How are alt modes implemented? What is the hardware like? 20:20 All USB Type-C cables & hardware have to be the same! CC (Configuration Channel) line starts handshake and is a dedicated pin Make sure cables only have one CC! 21:40 USB Type-C is reversible! 22:20 The device receptacle does the signal routing based on cable orientation How does device negotiation work? For example, what if two phones want to charge each other? 23:30 A device can be a host (sinking) or a device (sourcing) 24:20 How does it happen? 24:45 RP, RD, RA resistor network is fundamental to Type-C RP means "always a source" RD means "always a sink" These networks have certain values that determine current, etc. 24:20 You can have Type-C without PD, up to 5V 3A. 26:00 Type-C PD lets you go to 20V 5A We have two USB test fixtures/USB test jig the N7015A and N7016A 26:30 Is USB PD available today? 26:45 Temperature sensors (or other fail safe mechanisms) are required 28:00 Are USB Type-C cables active or passive? 28:45 In general, USB Type-C cables are passive. Active USB Type-C cables will be used for longer cables. All cables have to have an e-mark chip to help with power negotiation 29:15 Not all USB Type-C cables can handle 100W USB Type-C can go up to 80 Gb data transfer using four TX/RX links! 31:00 There's room to grow for future USB Type-C revisions 32:10 Predictions 30:30 http://www.keysight.com
