Ag9311maq design 100W USB type C docking station data | ag9311maq is used for 100W USB type C to HDMI with PD fast charging +u3+sd/cf docking station scheme description

       ALGOLTEK Angstrom technology is in 2019 In, a new low-power single chip was introduced USB Type-C Audio and video format converter scheme ──AG9311 Will be for various displays 、 External display device 、 Seamless audio and video connection of digital TV and embedded display is provided USB Type-C DisplayPort Alt-Mode And DisplayPort Alt-Mode turn HDMI、SD/HDTV、DVI and VGA High cost-effective single chip solution .AG9311 Integrated belt PD3.0/PD3.1 Charging function , Support USB Type-C DisplayPort turn HDMI All functions of the output , And can expand USB 3.0HUB and 3.0 Card reader SD/TF Card function , Specifically AG9311 How to design belt 100W PD Quick charge +USB 3.0+SD/CF Card multifunctional docking station or extender products ？AG9311MAQ Design 100W USB TYPEC turn HDMI belt PD Quick charge +U3+SD/CF What are the advantages and characteristics of the docking station ？ Now we will explain them one by one .

AG9311MAQ Product design features ：
1.AG9311MAQ Can support PD3.0 The fast charging protocol is built-in PD chip , Saved PD Fast charging chip , Some peripheral circuits are reduced , Reduce BOM cost .
2.AG9311MAQ Not only support PD3.0 Fast charging protocol and support FSR function . Some support PD3.0 The expansion dock of , Unplugging （ Connected to the docking station ） When charging the line , Its body is connected HDMI And the device will flash off some and then reply , That's because the mode of power supply has changed , Before that was PD The charging end supplies power to the screen projection device , When PD After removal , our IC It will supply power to the screen projection equipment for a short time , And at the same time , our IC Will also inform HOST,PD Power supply failure , Let it power it out quickly , Our screen projection equipment will not have a black screen in the whole process 、 Flashing screen phenomenon . That's all AG9311MCQ And AG9311MAQ Chips with equivalent functions , Differences between different internal devices and different packages .
3.AG9311MAQ In addition to supporting PD3.0 Quick charge agreement , And it can expand some functions that other docking stations have , Such as USB HUB,USB Card holder ,RJ45 so ,3.5MM Independent audio signal output .
Sum up AG9311MAQ The above design advantages are due to the following advantages ：
1、 Show AG9311 accord with DisplayPort specification Revision 1.2AG9311 Support 1.62（RBR）/2.7（HBR）/5.4（HBR2）Gbps Data rate support 1/2 The line configuration supports downlink spread spectrum clock （SSC）AG9311 Support I2S Bus audio extraction

2、HDMI HD multimedia interface conforms to HDMI1.4 and HDCP1.4 The specification supports up to 3Gbps To minimize the transmission difference of AG9311 Supports resolutions up to [email protected] Output support HDCP Key pre programmed compatible EDID and MCCS Support sampling rate 48kHz/44.1KHz/32KHz Of LPCM Two channels

3、USB Type-C PD Support the display port standby mode protocol DisplayPortAlternate accord with USB PD3.0 Integrate Type-C RP and RD Resistor support 2 individual USB Type-C Port support USB Claim integration USB2.0 Full speed                                                                 

 4、 SCM system and interface integration 16 Bit MCU integrated for firmware upgrade 64KB Flash memory support I2C Lord / from 、UART、USB2.0 Full support 3 passageway 8 bit The resolution of the ADC5、 Power operation and ESD3.3V:3V to 3.6V operation 1.2V:1.08 to 1.32V function 1.2V Core power and 3.3V I/O Power Supply HBM 2KV ESD performance
