Type-C Overview

3

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

Type-C Power Delivery

6

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

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

USB-PD Test Solutions Overview

• N7020A PD Probe

• N7016A PD Test Fixture

• N8837A PD Decode SW

• N8833A Crosstalk Analysis SW

• Portfolio of Power Sources and Loads

• GRL USB-PD PHY Compliance Solution

USB 3.1 Gen1/Gen2 Receiver Test Setup

Key capabilities:

• Analysis of coded & retimed data

• Support of 8b/10b and 128b/132b HW coding and decoding as well as HW scrambling

• Generates calibrated stress conditions for RX test (SSC, SJ, RJ, De-emphasis, ISI)

• Emulate LFPS 3-level signals with built-in electrical idle for loopback training and via channel

• Integrated Link Training, Tx Eq, Noise Impairment, Variable ISI, Receiver

USB 3.1 Cable and Connector Test Solutions

New Compliance MethodologyChannel MetricsThere are three signal integrity impairments that impact the end-to-end link

performance: attenuation, reflection and crosstalk.

Reference: USB-IF Technical White Papers http://www.usb.org/developers/docs/whitepapers/

“Methodology Used to Determine SuperSpeed USB 10 Gbps (USB 3.1) - Gen2 Channel and Cable Assembly High Speed Compliance”

The channel metrics represents these three

impairments:

• Insertion loss fit at Nyquist frequency (ILfitatNq)

• Integrated multi-reflection (IMR)

• Integrated crosstalk (IXT)

Thunderbolt 3 Solutions

22

– Announced in Q2 2015

– 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

Thunderbolt 3 Overview

23

– 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.
