Overview

This design note describes methods for implementing high-resolution video solutions, such as UXGA, SXGA, and HD, using a single 5V power supply. It highlights the LT6556 as an input-port buffered multiplexer and ADC driver with a 750MHz bandwidth. For cable driving, it details the LT6557 and LT6558 triple amplifiers, which feature internal biasing to reduce component count for UXGA systems. Additionally, the document discusses the LT6559 triple current-feedback amplifier as a cost-effective solution for 1080p HD video. These devices eliminate the need for boost regulators or negative voltage rails, such as those provided by the LT1983-3, by offering near rail-to-rail output performance.

Use Cases

  • Multimedia video display systems requiring input selection
  • Driving analog-to-digital converters (ADCs) in video systems
  • UXGA-resolution cable driving with minimal external parts
  • Consumer video playback equipment for SXGA or 1080p HD
  • Output buffering for passive reconstruction filters
