Other Parts Discussed in Thread: DS90UB901Q-Q1 , DS90UB902Q-Q1 Dear sir,
We try to connect NS LVDS chips "DS90UB901Q-Q1/DS90UB902Q-Q1" to DM814x.
We found LVDS chip needs I2C "clock stretching" mode support on DM814x's I2C controller.
Could…
Hi Dang Tr,
There is an internal 25MHz oscillator on the Serializer. However, the 25MHz cannot be accessed directly and will be serialized by 28*PCLK onto the FPD-Link III data stream.
In camera mode, by default the Serializer is in a low-power Standby…
Part Number: DS90UB902Q-Q1 Hello, We use in combination of DS90UB901Q and DS90UB902Q. There is a issue that the LOCK signal of DS90UB902Q falls to low occasionally and CRC errors occur(Pass signal to high). We using Both DS90UB901Q and DS90UB902Q in Slave…
Hi He Dong,
Nice e-meeting you.
If your system has the I2C master attached to the DES, i.e. looks like this: Imager / EPROM <--> SER <--> DES <--> SoC (I2C master), the only configuration you need is to define the IDx and Aliases on the DES as you…
HI Dongbao,
I will have to look into this and get back to you. In the meantime here are two I2C appnotes that apply to FPD3 devices.

Also,
In case you have not seen these yet, here are two app notes that discuss I2C communication over FPD-Link:
