Transmitter Connects To Low-Power Embedded Processors Without Glue
The Texas Instruments SN75LVDS83B low-voltage differential signaling (LVDS) serializer connects to 1.8-V powered processors. It utilizes the company’s FlatLink technology and removes the need for an expensive level shifter when using 1.8-V and 2.5-V logic interfaces, which reduces cost by more than 1$ and board space by up to 83% with the BGA package and 39% with the TSSOP package, says TI. The device sustains 8-bit color and serializes RGB data, before combining 24 data lines into one LVDS clock and four LVDS data pairs that attach to LCD modules. ...
