3 Type-C Overview 3

4 Industry Drivers for Type-C New form-factor Smaller size Reversible plug orientation Reversible cable direction Establishes power delivery Scalable charging to 100W Power direction, data direction, Vconn swap Enables adoption by other standards ALT (Thunderbolt, DisplayPort, MHL, HDMI) and Accessory Mode (Audio) Future scalability Legacy Compatibility USB 2.0, USB 3.1 Gen 1, BC 1.2 5V Vbus start 4

5 USB Type C-Signal Plan 5

6 Type-C Power Delivery 6

7 USB-PD vs Type-C vs USB speeds Is Type-C the same as USB-PD? Can Type-C not implement PD? Must USB 3.1 implement Type-C? Does USB 3.1 require PD? Can USB 2.0 implement Type-C? Does USB-PD require Type-C? Must a charger implement Type-C? How do you tell if a product has PD implemented? Can USB 3.0 implement Type-C? Will PD compliance be mandatory? 7

8 Type-C Power Delivery Testing 3 Chapters (PHY, Protocol, Power) in the Power Delivery Spec responsible for: Charge devices up to 20V/5A/100W Cable functionality Provider/Consumer 8

19 New Compliance Methodology Channel Metrics There are three signal integrity impairments that impact the end-to-end link performance: attenuation, reflection and crosstalk. The channel metrics represents these three impairments: Insertion loss fit at Nyquist frequency (ILfitatNq) Integrated multi-reflection (IMR) Integrated crosstalk (IXT) Reference: USB-IF Technical White Papers Methodology Used to Determine SuperSpeed USB 10 Gbps (USB 3.1) - Gen2 Channel and Cable Assembly High Speed Compliance 19

21 USB 3.1 Cable/Connector Compliance Test Typical Configuration ENA Mainframe [1] E5071C-4D5: 4-port, 300 khz to 14 GHz E5071C-4K5: 4-port, 300 khz to 20 GHz Enhanced Time Domain Analysis Option (E5071C-TDR) ECal Module (N4433A) [1] 20 GHz option is recommended, since the Type-C cable/connector requires measurements up to 15 GHz. [2] The list above includes the major equipment required. Please contact our sales representative for configuration details.

22 Thunderbolt 3 Solutions 22

23 Thunderbolt 3 Overview Announced in Q Uses the Type-C connector Channel aggregation: two independent 20Gbps links into one logical 40Gbps link Supports other standards through ALT mode Cost competitive vs mult chip, discrete, mux solutions 23

24 Testing Methodology PHY testing approach will be similar to Thunderbolt 2 Tx, Rx, and Return Loss Plus Type-C Power Delivery DP, USB over Type-C Customers with Thunderbolt DUTs need to work with their Intel PAE or authorized test house for compliance certification Keysight can help with pre-compliance testing and is authorized in CTS for TX, RX, and Return Loss. 24
