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.

MHL -> HDMI MHL
SOURCE DUT
HDMI OUT
This is an HDMI output. The device it gets connected to depends
on the source test application.
For basic functional testing of an MHL source - An HDMI
cable is connected to the HDMI IN port on an HDTV to
monitor the video and audio.
For basic protocol testing of an MHL source – An HDMI cable
is connected to an HDMI input on the 882EA or 780 to check
the timing and protocol data or to check the response to
various EDIDs.
For HDCP compliance testing of an MHL source – An HDMI
cable is connected to a port on the Encryption Status Tester
(EST).
MHL IN
FROM DUT
Connect MHL cable from MHL source device under test, e.g.
mobile phone.

HDMI -> MHL
MHL SINK DUT
HDMI IN
This is an HDMI input used for HDCP compliance testing of MHL
sink devices. An HDMI cable is connected to the Encryption Status
Tester (EST) used with the 882EA HDMI output. For basic
functional testing of an MHL sink device, an HDMI source devices
or 780 Handheld Test Instrument is connected to this port.
MHL OUT
