10 Texas Instruments

Analog The TFP410 is a DVI 1.0-compliant digital transmitter that supports display resolutions ranging from VGA to UXGA in 24-bit, true-color pixel format. Some of the advantages of this universal interface include selectable bus widths, adjustable signal levels, and differential and single-ended clocking. The adjustable 1.1- to 1.8-V digital interface provides a low-EMI, high-speed bus that connects seamlessly with 12- or 24-bit interfaces.

When an LCD display is used in the system, LCD power, LED backlight and touch-screen controllers should be considered. The TSC2046 is a four-wire touch-screen controller with an on-chip 2.5-V reference that can be used for the auxiliary input, battery monitor and temperature measurement modes. The TPS61042 is a high-frequency boost converter with constant-current output that drives white LEDs for LCD backlight.
