AG9311MAQ design USB TYPEC to HDMI with PD3.0 fast charge+USB3.0+SD card/TF card+3.5MM headphone output expansion dock design method
AG9311MAQ is a USB TYPEC to HDMI built-in PD fast charging audio and video conversion solution. AG9311MAQ has 4 LAN signal outputs. In addition to one HDMI signal output, it can also expand other functions, such as USB3.0 card reader, II2S audio signal output, 100M/Gigabit Ethernet port output, USB3.0/3.1 HUB output, etc.
The detailed parameter characteristics of AG9311MAQ are as follows:
AG9311MAQ can easily design TYPEC to HDMI with PD3.0 fast charge+USB3.0+SD card/TF card+3.5MM headphone output expansion dock based on some of the parameter characteristics in the above figure:
AG9311MAQ design TYPEC to HDMI with PD3.0 fast charge+USB3.0+SD card/TF card+3.5MM headphone output expansion dock Features:
1. AG9311MAQ can support PD3.0 fast charge protocol with built-in PD chip, which saves PD fast charge chip, reduces some peripheral circuits, and reduces BOM cost.
2. AG9311MAQ not only supports PD3.0 fast charge protocol but also supports FSR function. For some docking stations that support PD3.0, when the charging cable (connected to the docking station) is unplugged, the HDMI and devices connected to the body will flash off and then resume. That is because the power supply mode has changed. The previous one was PD charging. When the PD is removed, our IC will provide power to the projection device for a short period of time. At the same time, our IC will also notify the HOST that the PD power supply fails, so that it can quickly power it out. During the process, our projection equipment will not have black screens or flickering screens. The above is the difference between AG9311MCQ and AG9311MAQ chips with the same function, different internal devices and different packages.
3. AG9311MAQ not only supports PD3.0 fast charging protocol, but also can expand some functions that other docking stations have, such as USB HUB, USB card device, RJ45 network port, 3.5MM independent audio signal output and so on.
