Description
A223804 USB-C signal module can support various required testing functions for USB-C interface not only basic Data transmission (Pass-Thru), USB PD (Power Delivery) functional test, DisplayPort Alternate Mode functional test but provide Status Monitor for users to check the characters and parameters of current status of equipment’s communication, and support programmable auto inspected function simultaneously for users to edit a Test Program to achieve automatic testing with one button.
DP Alternate Mode Test Function
Video Electronics Standards Association VESA announced DisplayPort Alternate Mode (Alt Mode) will be supported via USB Type-C. By DisplayPort Alt Mode，which utilizes USB Type-C interface and connection cable to provide a complete video output. A223804 USB-C signal module supports DisplayPort 1.3 Alt Mode and the bandwidth transmission can up to HBR2(High Bit Rate 2, 5.4Gbps), and supports 4K(4096×2160)@60Hz for video testing. It is also equipped with HDCP (High-Bandwidth Digital Content Protection) 1.4 and 2.2 testing function.
USB Pass-Through Test Function
In USB data transmission (Pass-Through), USB-C supports the latest USB3.1 standard among USB 3.1 Gen1 which is compatible for the main third revised version of Universal Serial Bus (USB). Compare to 480Mb/s half-duplex USB 2.0, USB 3.1 Gen1 is capable for 5Gb/s full-duplex for writing and reading simultaneously which is ten times transmission improvement. A223804 supports USB Pass-Thru testing function for user not only focusing on determining data version of the interface, but through real transferred document to do actual rating test to ensure the rate of the product is compliance with the standard requirement.
Power Delivery Test Function
The charging interfaces for laptops and mobile phones varies greatly, and the chargers between different brands and models are mostly incompatible. Therefore, USB-IF association promotes the USB Power Delivery power transmitting protocol, which became more popular recently for devices to support USB PD charging, including cell phones, digital cameras, mobile devices, external storages, laptops and monitors, allowing charging, data transmission and video playback all to be supported by one single cable.
In PD 2.0 standard, the power specification is defined at a maximum of 100W(20V/5A). To accommodating this requirement, an External Power Unit is designed to support the A223804 USB-C Signal Module to support the power testing up to 100W. The External Power Unit is adjustable to switching between Power Roles, to match the different voltage and current specifications of the unit under test.
Programmable Automated Test Function
The A223804 signal module supports programmable automated test function for users to edit the USB-C Test Program according to the specs of the unit under test. Test items including DP Alt Mode video output, Power Delivery VBUS / CC Pin testing, PDO setting parameter comparison, Pass-Through speed testing, cable flip and other required USB-C testing. The test results are directly shown on the monitor, or could be retrieve by commutation commands. Users will be benefited by uploading the test results to the SAP system from the test-result retrieving function.
