USB EZ-PD™ Type-C Forum Discussions
Hi, Sir,
1. Could you please provide us the command line too for CCG3 FW update?
2. We need a command line for FW updating that also can specify VID/PID , becuase we will modify CCG3's billboard's VID/PID

Show LessHi!
We are looking (again) at developing a DisplayPort 1.2 Input + USB 3.0 Input to USB-C (DFP) adapter. The CCG3 Host reference design is more or less the design we are looking at, but we had one key question:
If we want to allow Pin Assignment D (2 lanes DP and 2 lanes USB 3), will that work when a upstream laptop is connected via legacy DisplayPort 1.2 cable? Will that laptop get information via AUX that it should provide only 2 lanes DP? Since the laptop will not be part of the PD signalling regarding C or D pin assignment.
What we "fear" is that the laptop will always default to 4 lanes DP on the DP output and not be informed about the need to only deliver 2 lane DP on lane 0 and 1.
Since Cypress host reference design has a DP 1.2 input and it apperently works when connecting a laptop via a DP cable to it, maybe it is not a problem?
Cheers
Olof
Show LessHello support team,
I hope you are doing well. We are implementing the USB C (from apple MAC) to USB 3.0 Gen 1 hub along with HDMI port with 4K @ 30Hz. In our case we are will sinking from the laptop and on our side we will only get power from laptop USB-C. We have already selected rest of the chips except the cross switch for USB and DP lines along with PD Alt mode IC. Can you please suggest the options that are in-stock and can easily be sourced?
I was looking at CYPD1120 (PD Alt Mode controller) but it is no where available, we would like to know if Cypress has any alternative that we can use?
Secondly, do you have any recommendation for the sink switch? I am reviewing cypress USB-C based development board reference design where you are using PS8742B as sink switch. In our case if you don't have a direct part for the switch then please confirm if your PD controller will support the DP Alt Mode for TI based cross switches like TUSB564RNQT?
Lastly, if our USB hub chip supports billboard then can we skip the separate billboard IC to reduce the board space and cost? Please note that we are using USB5806/KD from Microchip.
Kind regards,
Muhammad Awais
Show Less能否用包含CCG3PA的CYPD3171芯片通过PD协议来引出其他TypeC端口24V的电压,现在最多通过PD能引出20V,datasheet上能我看芯片是支持3V~30V的电压的,用EZ-PD configuration uility配置试了一下也不行,不知道怎么配置
Hi All,
I want to make a Type-C to eDP monitor dongle, reference to 3120 type-c to dp dongle.
With connected SBU1/2 into IC and AUXp/n out to eDP monitor, my PC can not recognizing any monitor. So I connected the SUB1/2 to eDP monitor AUXp/n directly, then my PC can recognizing a 4K"wired link monitor", but my eDP monitor show "blank screen". It's a 15.6" eDP 4K monitor, the back light is OK.
Any and all suggestions would be most appreciated, thanks.
Best Regards,
King
Show LessHello
Please find attached image.
# 1 Connect the smartphone via HDMI and display the
Smartphone screen on the monitor
# 2 Type-c output / HDMI output of microphone sound from
The development unit
Q1) Which type-C signal line is best to use and how to operate #1 and #2 above?
Q2) Is it possible to get only audio (analog signal) from type-c (video / audio)? What kind of method is it?
Q3) How can I convert audio (analog signal) to type-c (audio)?
Q4) Is there a way to get only audio (analog signal) from HDMI (video / audio)?
Best Regards

Show LessDear,
Does CYPD4236 Example have I2C_Write() but no I2C Read.
If I also need to use I2C Read, is there a reference example that I can use?

Show LessDear Sir
CYPD3171 Sink only how to trigger VBUS OVP ?
Hi,
Are there any updates to the CCG3PA stack so that the device can be updated via UART or I2C?
it's ok to flash it once via SWD, but on the field we can't rely on SWD nor CC to upgrade the firmware.
Thanks
