Product Summary
The AD724JR is a low cost 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 to provide composite video output. All three outputs of AD724JR can simultaneously drive 75 W, reverse-terminated cables. All logical inputs are TTL, 3 V and 5 V CMOS compatible. The chip operates from a single +5 V supply. No external delay lines or filters are required. The AD724JR may be powered down when not in use. The applications of the AD724JR include RGB to NTSC or PAL Encoding.
