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.

The SN75LVDS83B supports netbooks, mobile Internet devices, digital picture frames, and other applications requiring an LVDS link from a processor to the LCD module. It sustains a pixel frequency range from 10 MHz to 135 MHz, which appears in high-definition (HD) screens. The product also works with OMAP35x applications processors and digital media processors founded on Texas Instruments’ DaVinciTM technology.

Featuring a direct connection to any transistor-transistor logic (TTL) level from 1.8 V to 3.3 V, the device eliminates the requirement of additional components. The SN75LVDS83B is available in a 56-pin TSSOP package at $2.60, and a 56-ball BGA package at $2.80. The SN75LVDS83A is only available in the 56-pin TSSOP package, has a maximum frequency of 100 MHz, and supports only 3.3-V input levels. It can be purchased for $2.10. All prices pertain to 1000-unit quantities.
