AG9310 Same function alternative |CS5261 replace AG9310Type-C turn HDMI Single switch screen scheme | low BOM replace AG9310 Design
Capstone CS5261 It can completely replace and be compatible with functions AG9310, Not only can Type-C turn HDMI 4K30HZ Single turn design , It can also be replaced with the same function on some slow charging dock products AG9310, Let's talk about that in more detail CS5261 And AG9310 Function overview and parameter differences , And low BOM Advantages of cost substitution .
AG9310 Function Overview
AG9310 It's a realization USB Type-C turn HDMI Data converter . Support USB Type-C Show port override mode ,AG9310 You can stream video and audio from USB Type-C Interface to HDMI port . stay AG9310 in , Support 1 road 、2 road @1.62Gbps、2.7Gbps and 5.4Gbps Different configuration of frequency input ,HDMI Support [email protected] Output . Product manufacturers can use AG9310 Applications are easy to implement Type-C turn HDMI Data converter transfer .
CS5261 Function Overview
CS5261 Integrated DP1.4 Compatible receiver , One HDMI2.0b Compatible transmitter . Besides , It also includes two CC controller , be used for CC signal communication , In order to realize the DP Alt Mode and power transmission （5V Slow charging ） function , One for upstream TYPEC port , The other is for the downstream port .DP Interface includes 2 Main channel 、 Auxiliary channels and HPD The signal . The receiver supports a maximum of 5.4Gbps（HBR2） Data rate .DP The receiver contains HDCP1.4 Content protection scheme with embedded key , For the secure transmission of digital audio and video content .
To sum up ：
CS5261 And AG9310 As a standard USB type CTM Display Port Alt Mode receiver , It consists of two main chains

The difference is right , An auxiliary channel differential pair , Two channel differential pair , Be able to operate HBR2（5.4-Gbps）、HBR（2.7-Gbps） and RBR（1.62-Gbps） Data rate , For HD uncompressed video transmission . The main link fully conforms to Display Port TM v1.4 standard .HDMI The link speed of each channel at the output is up to 3 Gbps, Allow to use 30Hz Refresh rate and 8 Bit color depth display 3840x 2160.

To sum up ：
CS5261 Not only can it completely replace AG9310, And the whole chip BOM Cost ratio AG9310 Be low , Designing circuits is also simple and easy , Chip integration ratio AG9310 higher , It mainly has the following advantages ：

1. Embedded oscillator , No external crystals are required , Reduce the board frame and save devices , cost reduction .

2. The embedded MCU And Serial flash, It can be updated online at any time FW, Compatible with more devices ： mobile phone , The computer 、 Plate etc. .

3. The embedded EDID（ If the terminal device does not ,CS5261 Will respond EDID）, The screen display is stable without delay .
