Part Number: DS90CF384AQ-Q1

Hi Sir,

My customer is looking for a solution which can support input 1.8V LVDS and output 3.3V TTL RGB bridge IC,

Is DS90CF384AQ-Q1 suitable for them? If not, pleas suggestion the right solution.

The topology as below

MTK MT2712C (LVDS) --> Bridge IC (DS90CF384AQ-Q1)--> 3.3V TTL RGB (800 x 480) display

If we don't have right solution for LVDS to RGB, do we have one chip solution for MIPI-DSI to RGB?

Because MTK MT2712C can config to LVDS or MIPI-DSI output. so if we have MIPI-DSI to RGB bridge IC, it is also good for my customer.

Please advice.

Thank you

Is the input Vcm of your LVDS signl 1.8? The DS90CF384AQ-Q1 has a Vcm of 1.2V which is compliant with spec. It has a 100 mV swing up and down.

MTK MT2712C output LVDS with 1.2V, so I think it is okay from LVDS to RGB888 with 88*480 resolution, am I correct?

Hi Anne,

What does the customer mean by "1.8V LVDS" in your first post? Do they mean they want the device power (ie Vcc) to be powered off 1.8V? The DS90CF384AQ-Q1 is powered off 3.3V, not 1.8V.

Regards,

I.K.
