Hi,

I'm using DS90CF386. I have some questions about this chip. Could you please help me?

1. The input data of the LVDS to RGB and time sequence is 1:1 or 7:1?

2. The LVDS output voltage level is 2.5V, then the input of DS90CF386 must be 2.5V or 3.3V?

3. Is there any user guide about this chip?

4. The chip will output the same data with input? or the input data must be the correct format?

Thanks.

Hi Kevin,

1. If you are asking if the clocking of the TX/RX data is the same, you may refer to figure 1.

2. Vcc = 3.3

3. You may find this user guide which is an evaulation kit containing the DS90C385A/DS90CF386 (TX/RX) board http://www.ti.com/lit/ug/snlu032a/snlu032a.pdf. Otherwise, technical documents are available at this link . http://www.ti.com/product/DS90CF386/technicaldocuments

4. Your input data should always be in the correct format. Your input data is four LVDS data streams + CLK , and output is parallel 28 bits of LVCMOS data.

Thanks,
Sally
