Product Overview

The AD725ARZ is a RGB to NTSC/PAL Encoder with Luma trap port. The general purpose RGB to NTSC/PAL encoder that converts red, green and blue color component signals into their corresponding luminance (baseband amplitude) and chrominance (subcarrier amplitude and phase) signals in accordance with either NTSC or PAL standards. These two outputs are also combined on-chip to provide a composite video output. All three outputs are available separately at voltages of twice the standard signal levels as required for driving 75W, reverse-terminated cables. The AD725 features a luminance trap (YTRAP) pin that provides a means of reducing cross color generated by subcarrier frequency components found in the luminance signal. For portable or other power-sensitive applications, the device can be powered down to less than 1mA of current consumption. All logic levels are TTL compatible thus supporting the logic requirements of 3V CMOS systems.
  • Both NTSC and PAL composite video output
  • Chrominance and luminance (S-video) outputs
  • Luma trap port to eliminate cross color artifacts
  • TTL logic levels
  • Integrated delay line and auto-tuned filters
  • Drives 75V reverse-terminated loads
  • Low power +5V operation
  • Power-down to <1mA
  • 800mW Internal power dissipation
