Look for new episodes each 2nd and 4th Thursday.

What is the EEs Talk Tech podcast?
What is USB Type-C, one port to end all others!
Show and tell
-Superspeed USB, micro USB
USB Type-C cables are the same on both ends
Host/Device Source/Sink vs role negotiation
USB Power Delivery (USB PD) overview
USB PD for USB A was deprecated
USB Type-C charger has 60 watts of power!
Charge your phone very quickly using USB PD 10:00
5V is an hobby-industry standard level, what about going forwards?
What does USB Type-C look like for day-to-day life? LED projectors? USB Noodle makers?
Q: Can I find a cheap USB Type-C cable? Should I?
A: Probably over time, but if it’s poorly made it could go badly
Phones are literally blowing up!
The cable isn’t just a wire anymore 14:59
USB alt modes:
USB is the cable to end all cables!
It can handle Displayport, HDMI, VGA, DVI, Thunderbolt, ethernet, power, headphones
MHL device discussion
No headphone jack needed!?!
Is USB Type-C available in stores?
Are manufacturers pushing Type-C or are consumers demanding it?
USB A to C, USB B to C, Thunderbolt to USB C adapters are allowed in the USB C spec (USB Type-C specification)
Make sure to look for USB Certification when you buy products
USB IF mandates that products be certified before being sold
A bad USB Type-C implementation can destroy your stuff!
How are USB alt modes implemented?
What makes up the hardware? 20:20
All USB Type-C cables & hardware have to be the same!
CC (Configuration Channel) line starts the 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 position and orientation
How does device negotiation work? For example, what if two phones want to charge each other?
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
What do the resistors mean?
RP means “always a source”
RD means “always a sink”
These resistor networks have certain values that determine current, etc.
You can have USB Type-C without PD, up to 5 Volts 3 Amps
USB Type-C PD lets you go to 20V 5A
Is USB PD available today?
Temperature sensors (or other fail safe mechanisms) are required 28:00
Are USB Type-C cables active or passive?
In general, USB Type-C cables are passive. Active USB Type-C cables will be used for longer cables.
All USB Type-C cables are required 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!
There’s a lot of room to grow for future USB Type-C revisions 32:10
