TXB0108: TXB0108DQSR - RGB interface

RSV

Prodigy 165 points

Part Number: TXB0108

We are using TXB0108DQSR level translator for level translation of RGB interface from 3V3 to 1V8.

The Operating frequency is 20MHz.

Port A is connected to LCD and Port B is connected to Controller. VCCA=1.8V and VCCB=3.3V

The trace lengths of RGB signals in Port A of TXB0108 will be around 3 inches.

Will this work correctly?

Hi Sakthivel,

The max data rate the TXB can support according to the datasheet is 60Mbps at 15pF loading CL.
I would assume that the loading on the output channel is not going to be more than 10-20pF with only the traces included. so, this should work fine.
If possible, ideally, shorter output traces would be good to reduce the parasitic cap load.
