As shown above, CS5266 and AG9311 are completely identical in function. In addition, CS5266 has a built-in oscillator, no external crystal is required, and an embedded MCU can update FW inside the chip. The update method is simple and easy to operate. It has an embedded EDID and does not require a driver after the device is inserted. It can automatically link the device for screen projection.

The circuit design schematics of the Type-C to HDMI+PD+U3s three-in-one docking station solution designed by CS5266 and AG9311 are compared as follows:

In summary: AG9311 circuit design is more complex, with more peripheral components, CS5266 design is simpler, with fewer peripheral components than AG9311, the overall design cost of CS5266 is lower than AG9311, and the chip cost is 20% lower than AG9311. The detailed comparison between CS5266 demoboard h and AG9311 demoborad is as follows:

From the above, we can see that the board size is smaller than that of CS5266, and CS5266 has fewer design components.

CS5266 replaces AG9311 to design the PCBA board of Type-C to HDMI+PD+U3 three-in-one Golden Docking Station as follows:
