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.

Quantum Data MHL Solutions
Quantum Data offers a comprehensive suite of test solutions for testing MHL source and sink
devices. The centerpiece of these solutions is a test point adapter (TPA-MHL-8R) that converts
MHL streams to HDMI and HDMI streams to MHL. The TPA-MHL-8R facilitates basic sink
emulation, functional testing, protocol analysis as well as HDMI compliance testing and HDCP
compliance testing for MHL source and sink devices. Protocol analysis and HDMI Compliance
testing requires the Quantum Data 980 Protocol Analyzer (297MHz module). HDCP compliance
testing requires the Quantum Data 882EA.
