1 Overview of MHL
Mobile High-Definition Link (MHL) is a video interface derived from HDMI but targeted to provide an interface from
mobile devices like smart phones to TVs or other displays. The MHL standard is designed to connect to smart
phones by reusing the existing 5 pin micro-USB connector that many phones have rather than requiring a separate
19 pin HDMI connector. The MHL cable is micro-USB on the source mobile device and HDMI Type A on the other
end.
1.1
Scope of this Quick Start Guide
This Quick Start Guide provides application information for testing your MHL 1.3, 2.0, 2.1 source or MHL 1.3, 2.0, 2.1
sink device. Procedures for connecting up the TPA-MHL2-8R are provided in this Guide. Procedures for MHL
protocol analysis and MHL compliance testing for MHL 1.3, 2.0, 2.1 sources and sinks are provided with the 980
Protocol Analyzer Compliance Test User Guides for sources and sinks. Detailed procedures for testing HDCP on
MHL sources and sinks are provided in the 882EA User Guide.
Note: Please be sure to check the Quantum Data website for updates to this Quick Start Guide.
2 Quantum Data MHL Solutions
Quantum Data offers a comprehensive suite of test solutions for protocol, video and audio compliance testing MHL
1.3, 2.0, 2.1 source and sink devices. The centerpiece of these solutions is a new test point adapter (TPA-MHL2-8R)
which replaces the TPA-MHL-8R. The TPA-MHL2-8R makes the necessary conversions between MHL and HDMI
streams for MHL 1.3, 2.0, 2.1 devices. The TPA-MHL2-8R supports protocol analysis as well as compliance testing
and HDCP compliance testing for MHL 1.3, 2.0, 2.1 source and sink devices. Protocol analysis and MHL Compliance
testing requires the Quantum Data 980 HDMI Protocol Analyzer module. HDCP compliance testing requires the
Quantum Data 882EA.

4 MHL Applications for Testing MHL Sink/Dongle Devices
This section describes the MHL test applications supported by Quantum Data test instruments and utilities for testing
MHL sink/dongle devices.
4.1
MHL Sink Functional Testing
You can run a functional test on an MHL sink using the TPA-MHL2-8R and an HDMI source device. However there
are a couple important notes to be aware of about the limitations of functional testing at 1080p60 format resolution.
Note 1: For functional testing of an MHL 1.3, 2.0, 2.1 sink device, you will have to switch to and from Packed Pixel
mode using commands if you want to test 1080p60 resolutions. These commands are only supported
through the Quantum Data 980 and 882.
Note 2: You will not be able to test an MHL 1.3, 2.0, 2.1 sink device with HDCP encrypted content through the TPAMHL2-8R.
Refer to the diagram below for a depiction of the test setup.
